Abstract:
Le soleil émet une multitude de rayonnements électromagnétiques filtrés par l’atmosphère terrestre. Arrivant à la surface de la planète, ces rayonnements sont indispensables pour l'installation et le développement de la vie. Le spectre solaire au sol comporte les ultraviolets (UV) B (290-320 nm) et les UVA (320-400 nm), la lumière visible et des infrarouges (IR). Les UV activent des molécules, appelées chromophores, contenues dans la peau et qui sont susceptibles de se modifier et ils déclenchent ainsi une cascade de réactions photochimiques ayant des conséquences biologiques et cliniques majeures. Les effets peuvent être soit aigus, soit d'apparition rapide et généralement de courte durée, ou chroniques, d'installation progressive et de longue durée. Les exemples des effets aigus comprennent les coups de soleil et la production de vitamine D, alors que le photovieillissement et le cancer de la peau sont les résultats d'une exposition chronique depuis de nombreuses années. Si le soleil est indispensable à la vie, son énergie potentiellement destructrice impose à l'homme de savoir l'apprivoiser et de photoprotéger sa peau.

Abstract:
Two‒dimensional IR correlation spectroscopy (2D‒IR) is a novel method that provides the analysis of infrared spectra with the capacity to differentiate overlapping peaks and to distinguish between in‒phase and out‒of‒phase spectral responses. Artificial spectra originated from protein amide I band component parameters have been used to study their variation in the correlation maps. Using spectra composed of one, two or three Gaussian peaks, behaviour patterns of the bands in the synchronous and asynchronous maps have been originated, with changes in intensity, band position and bandwidth. Intensity changes produce high‒intensity spots in the synchronous spectra, whereas only noise is observed in the asynchronous spectra. Band shifting originates more complex patterns. In synchronous spectra, several spots are generated at the beginning and at the end of the shifting band. Also, characteristic asynchronous spectra with butterfly‒like shapes are formed showing the trajectory of the shift. Finally, synchronous maps corresponding to band broadening reveal several spots at peak inflection points, related to the zones with higher intensity variation. The asynchronous spectra are very complex but they follow a characteristic symmetric pattern. Furthermore, examples of maps obtained from polypeptides and proteins using temperature as the perturbing factor are interpreted in terms of the patterns obtained from artificial bands.

Abstract:
L'étude du pouvoir réflecteur (r) et de la transmission (t) des milieux anisotropes et absorbants dans l'infrarouge lointain nous a conduit a présenter des expressions directement programmables des relations permettant la détermination des constantes optiques, l'indice de réfraction n et l'indice d'absorption k à partir des mesures expérimentales de r et de t. Nous avons établi les expressions des facteurs de réflexion et de transmission pour les deux polarisations possibles de l'onde, en fonction de l'angle d'incidence. L'étude est limitée au cas de la propagation d'une onde plane dans les plans principaux du cristal. Nous abordons ensuite le cas de la lame à faces parallèles qui représente physiquement nos échantillons. Les facteurs de réflexion et de transmission sont mesurés dans l'infrarouge lointain de 10 à 600 cm##1 en lumière polarisée pour des températures comprises entre 7 et 300 k. Pour cette étude nous avons choisi un cristal biaxe, le nitrite de sodium et deux cristaux uniaxes, la cassitérite et le quartz. La comparaison des résultats expérimentaux et des valeurs calculées nécessite la connaissance de la fonction diélectrique. Nous utilisons la forme factorisée de la fonction diélectrique. Les valeurs initiales des paramètres d'ajustage sont déterminées par une analyse de Kramers-Kronig du spectre de réflexion sous incidence normale. La mesure simultanée du pouvoir réflecteur et de la transmission de la lame nous permet d'apporter une correction pour déterminer la valeur vraie du pouvoir réflecteur des cristaux, valeur nécessaire pour les calculs de physique du solide

Abstract:
La photorotamerisation induite par irradiation infrarouge selective du 1,2-dideuterioethane ch#2d-ch#2d piegee en matrices de gaz rare pose le double probleme de la relaxation intramoleculaire du mode excite sur le mode de rotation interne et de la relaxation intermoleculaire par interaction de l'espece excitee avec son environnement. Cette molecule presente deux conformeres stables (une forme gauche de symetrie c#2 et une forme trans(anti) de symetrie c#2#h). Nous avons montre que la molecule piegee en matrice de xenon presente un mode b a 1046,85 cm#8#1 de la forme gauche du ch#2d-ch#2d resonnant avec la raie p20 du laser co#2. On peut supposer que la barriere autour de la liaison c-c est peut differente de celle de l'ethane, c'est-a-dire 12,1 kj. Mol##1 soit 1012 cm##1. C'est-a-dire une energie de l'ordre de grandeur de celle du photon co#2. Le processus de photoconversion gauche-trans induite par l'absorption d'un photon infrarouge conduit a une forte modification des populations entre les differents conformeres. L'analyse de la cinetique d'idomerisation met en evidence deux phenomenes majeurs: l'existence d'un effet et tunnel permettant l'isomerisation inverse sans irradiation a travers la barriere de potentiel; l'existence d'un couplage non selectif entre les modes vibrationnels trans, gauche et la rotation interne, lorsque la molecule est irradiee par une source a large bande. Les etudes preliminaires de sites de piegeage traduisant l'interaction de la matrice sur la molecule active ont ete realisees avec l'ethane dont la symetrie d#3#d est parfaitement bien adaptee a celle d'un site monosubstitue dans un cristal cubique a faces centrees. L'hypothese d'un site disubstitue est aussi envisagee. Dans ce cas l'apparence des spectres et leur comparaison avec ceux de l'ethane gazeux permettent d'envisager l'hypothese d'une rotation de la molecule dans le site d'argon. La ro

Abstract:
Ce travail est essentiellement consacré à la synthèse et l'étude de couches minces amorphes obtenues à partir de matériaux lamellaires polycristallins du type LixV₂ 0₅ (0 ≤ x ≤ 0. 2 ), M¹¹PS₃ ( M =Mn, Fe, Ni, Cd, Sn et ln2/3). La préparation de matériaux présentant une stœchiométrie correcte a nécessité la réalisation d'un dispositif d'évaporation flash permettant de travailler avec une température de 1500° C, et adapté pour tremper cette vapeur à la température de l'azote liquide. Les films amorphes ont été caractérisés par microscopie optique et électronique à balayage, analyse chimique, spectroscopies I. R. Et UV-visible. Leurs propriétés de conduction électronique ont été étudiées et comparées avec celles de leurs homologues cristallins. L’arrangement atomique local (ordre à courte distance) de plusieurs phases MPS₃ a été étudié en utilisant la spectrométrie E. X. A. F. S. Les résultats montrent qu’au sein des couches minces on retrouve la même structure de base que dans les composés cristallins correspondants. Suivant le métal M, quelques variations sont toutefois observées. La possibilité d'utiliser ces films dans des dispositifs photovoltaiques a été étudiée. Les couches minces amorphes de V₂0₅ et Li0. ₁V₂0₅ ont des propriétés semi-conductrices de type n, et conduisent à une) jonction p-n photosensible quand elles sont déposées sur du silicium (p). Finalement, nous avons examiné la possibilité de synthétiser de nouveaux matériaux amorphes M₃Ps₄, soit par évaporation flash, soit par chimie douce, c'est-à-dire par réaction d'ions métalliques M+ dans l'acétonitrile avec le ligand PS₄ ³-
This work is essentially devoted to the synthesis and study of amorphous thin films obtained from lamellar crystalline materials such as LixV₂ 0₅ (0 ≤ x ≤ 0. 2), M¹¹PS₃ (M= Mn, Fe, Ni, Cd, Sn and ln2/3)The achievement of materials presenting a correct stoichiometry has required the realization of a flash evaporation device operating at 1500° C and adapted to allow quenching of the vapor at liquid nitrogen temperature. The amorphous thin films have been characterized by, optical and electron scanning microscopy, microscopy, microprobre, UV-visible and I. R. Spectroscopies. Their electrical conductivity has been studied and compared with the crystalline parent compounds. The local atomic arrangement (short range order) of several MPS₃ films has been studied using the E. X. A. F. S. Technique. Results show that the films have the same basic structure as the parent crystalline compounds, but deviati0ns are observed, depending on the metal M. The possibility of applying these films to design new photovoltaic devices has been examined. Amorphous V₂0₅ and LixV₂0₅ films have n type semiconducting properties and they lead to photosensitive p-n junction when deposited on to p type silicon wafers. Finally, we have examined the possibility of synthesing new amorphous M₃Ps₄ materials either by flash evaporation and by a novel soft chemistry, i. E.

Pour cela, les homologues n-hydroxyles de dipeptides protégés à leurs extrémités par une fonction amide ont été préparés et étudiés en solution par RMN et spectroscopie ir, à l'état solide par diffraction des rayons X, et soumis à une analyse théorique par dynamique moléculaire. Le premier chapitre est un rappel des connaissances nécessaires à la compréhension de la suite. Le second chapitre décrit la synthèse des n-hydroxypeptides examinés et les méthodes d'étude structurale utilisées. Les résultats sont exposés dans le troisième chapitre, et le quatrième chapitre est une discussion de ces résultats en relation avec les observations conduites sur des composés pseudopeptidiques voisins.

Abstract:
Les composés organiques volatils oxygénés (COVO), principalement émis par des sources biogènes, jouent un rôle majeur dans la chimie de l'atmosphère, le changement climatique, l'environnement et la santé. Il a été récemment démontré que ces émissions augmentent en cas de stress biotique et/ou abiotique. Les COVO biogéniques peuvent subir une variété de réactions, tant chimiques que photolytiques, et ils sont impliqués dans la formation d'Aérosols Organiques Secondaires (AOS). Ces composés ont été détectés dans diverses régions, mais il y a très peu d’informations sur leurs processus de dégradation sous conditions troposphériques. La compréhension des mécanismes d'oxydation de ces espèces est d'un intérêt fondamental et fournit des données cruciales pour les modèles atmosphériques qui sont utilisés par les responsables politiques pour formuler et décider des stratégies d'amélioration de la qualité de l'air. Cette thèse vise à améliorer les connaissances actuelles sur le comportement de ces COVO, pour une meilleure compréhension de leur impact sur la chimie atmosphérique. Dans ce travail, nous avons présenté une étude détaillée de la dégradation atmosphérique des aldéhydes insaturés en C5-C7 et des alcools insaturés en C5-C8 par ozone, l’atome Cl et le radical OH. Les principaux objectifs étaient de mieux comprendre le mécanisme de réaction et de mettre en évidence leur potentiel à former des AOS. Pour atteindre ces objectifs, nous nous sommes concentrés sur quatres volets : (i) détermination du spectre IR et UV des aldéhydes insaturés en C5-C7, (ii) détermination de la constante de vitesse pour les systèmes COVO + Oxydant étudiés à température ambiante, (iii) identification et quantification des produits en phase gazeuse, (iv) détermination des rendements en AOS. Les études sur les produits ont été menées avec et sans ajout d'un piégeur des radicaux OH. Les expériences ont été réalisées dans huit réacteurs différents, statiques (chambres) ou dynamiques (flux), et diverses techniques analytiques ont été utilisées pour étudier les produits de réaction (FTIR, GC-FID/MS, SPME-GC/MS, HPLC, PTR-ToF-MS, SIFT-MS, PLP-LIF) et la formation de SOA (SMPS, FMPS)
Oxygenated Volatile Organic Compounds (OVOCs), mainly released from biogenic sources, play a major role in atmospheric chemistry, climate change, environment, and health. These emissions have been recently shown to increase in the case of biotic and/or abiotic stresses. Biogenic OVOCs may undergo a wide variety of reactions, both chemical and photolytic, and they contribute in the formation of Secondary Organic Aerosols (SOAs). These compounds have been detected in various areas, but little is known about their degradation processes under tropospheric conditions. Understanding the oxidation mechanisms of these species is of fundamental interest and yields crucial data for atmospheric models used by policymakers in formulating and deciding strategies for improving air quality. This dissertation aims to improve the current knowledge of those OVOCs behaviors to better understand their impact on atmospheric chemistry. This work reports a detailed study of the atmospheric degradation of C5-C7 unsaturated aldehydes and C5-C8 unsaturated alcohols by ozone, Cl atom, and OH radical. The main objectives were to better understand the reaction mechanism and to feature the SOA formation potential. To achieve these objectives, we focused on four topics: (i) determination of IR and UV spectrum of C5-C7 unsaturated aldehydes, (ii) determination of the rate constant for the studied OVOCs + Oxidant at room temperature, (iii) identification and quantification of the gas-phase products, (iv) determination of the SOA yields. The product studies were investigated both with and without adding an OH radical scavenger. Experiments were performed in eight different static (chambers) or dynamic (flow) reactors, and various analytical techniques were used to investigate the reaction products (FTIR, GC-FID/MS, SPME-GC/MS, HPLC, PTR-ToF-MS, SIFT-MS, PLP-LIF) and SOA formation (SMPS, FMPS)

Ce mémoire concerne l'étude des propriétés optiques et magnéto-optiques dans le domaine visible proche infrarouge, de films de ferrite de cobalt de structure nanocristalline.

Ce matériau est un support potentiel d'enregistrement magnéto-optique à haute densité. L'obtention des spectres d'absorption des films à partir des données spectrophotometriques a nécessité la mise au point d'une méthode spécifique de dépouillement des données. Les résultats obtenus montrent l'existence de désordres topologique et magnétique croissant avec le flux d'oxygène, ce qui a déjà été révélé par des techniques macroscopiques. Les résultats originaux sont la mise en évidences d'une brisure de symétrie de l'environnement octaédrique des cations, et l'existence du désordre magnétique sur les deux sites cationiques du spinelle.

Abstract:
Etude théorique du spectre infrarouge de l'élongation X-H en liaison hydrogène faible : i) la densité spectrale est obtenue par transformée de Fourier de la fonction d'autocorrélation du moment dipolaire de la liaison hydrogène, ii) la liaison hydrogène est modélisée par trois types d'oscillateurs quantiques (rapide, lent et de torsion), iii) deux types de couplage sont pris en considération : couplage anharmonique fort entre les modes rapide et lent, et le couplage de Fermi entre le mode rapide et un ou plusieurs modes de torsion, iv) l'anharmonicité intrinsèque du pont hydrogène est intégrée conjointement à la prise en compte d'un seul couplage de Fermi, et ce au delà des approximations adiabatique et d'échange, v) dans le cadre des trois approximations adiabatique, harmonique et d'échange, la relaxation des trois types d'oscillateurs est introduite en présence de plusieurs résonance de Fermi, vi) dans ce dernier modèle, l'effet Doppler et la structure rotationnelle sont pris en compte. L'expérimentation numérique conduit aux conclusions suivantes : i) caractère très général des résonances de Fermi en liaison hydrogène. Ii) condition de résonance ne doit pas être nécessairement remplie. Iii) dans certains cas le nombre de fenêtres égale aux nombre de résonances. Iv) l'intensité relative des sous bandes et leur position dépendent fortement des valeurs des trois relaxations. V) anharmonicité intrinsèque du pont hydrogène décale le centre de la bande vers les hautes fréquences quand la température augmente. Vi) la structure rotationnelle en phase gazeuse explique la ressemblance des spectres en phases liquide et gazeuse
Theoretical study of the infra-red spectrum of X-H elongation in weak hydrogen bonds: i) the spectral density is obtained by Fourier transform of the autocorrelation function of the operator dipole moment, ii) the hydrogen bond is modelled by three types of quantum oscillators (fast, slow and bending), iii) two types of coupling are taken into account: strong anharmonic coupling between the fast and slow modes, and the coupling of Fermi between the fast and one or several bending modes, iv) the intrinsic anharmonicity of the hydrogen bridge is integrated jointly into the taking into account of only one coupling of Fermi, and this beyond the adiabatic and exchange approximations, v) within the framework of adiabatic, harmonic and exchange approximations, the relaxation of the three oscillators is introduced in the presence of several Fermi resonance, vi) in the last model, the Doppler effect and the rotational structure are taken into account. The numerical experimentation leds to the following conclusions: i) very general character of the Fermi resonances in hydrogen bonds. Ii) the condition of resonance should not be necessarily filled iii) in certain cases the number of windows is equal to the number of resonances. Iv) the relative intensity of lineshape and their position depend strongly on the values of three relaxations. V) intrinsic anharmonicity of the hydrogen bridge shifts the center of the band towards the high frequencies when the temperature increases. Vi) the rotational structure in gas phase explains the similitude of the spectra in liquid and gas phases

Abstract:
Abstract Ultraviolet–visible UV-VIS. Varian Bio Cary 100 UV–VIS instrument was used for measuring the spectrum of dust samples. The certified materials according to Lab sphere SRS. 99–020 were used and the dust samples were placed in a cuvette (10 mm) and placed on the diffuse reflectance accessory. Measurement was done with respect to the reference. The UV–VIS spectra cover the regions from 900 to 190 nm which includes the near-infrared region, visible light regions, and ultraviolet regions. The FT-IR data shows the different chemical content of dust in the scanning of what possible compounds can be found in dust particles for required further analysis. The dust absorption of the light spectrum in Kuwait was revealed in maps according to seasons showing higher and lower concentrations of light absorption of ultraviolet, violet, blue, cyan, green, yellow, orange, red, infrared.

Abstract:
Abstract Continuous development in the semiconductor process technology has led to the fabrication of devices with nanometer scale feature resolution. Resonance enhanced atomic force microscopy infrared (AFM-IR) is a novel technique with potential to overcome some limitations of existing tools. This manuscript illustrates chemical characterization of the nanoscale skin and polyester contaminant on silicon wafer using resonance enhanced AFM-IR spectroscopy. Resonance enhanced AFM-IR offers superior sensitivity for nanoscale organic contaminants. To demonstrate this capability, AFM-IR spectra were obtained from contaminants on silicon wafers, and the spectra correlated with a high confidence to a standard transmission FTIR spectral database. In addition, a newly developed high speed spectral acquisition scheme, which augments the reliability of nanoscale defect characterization by reducing the overall data acquisition time and enabling users to perform repeated measurements for statistical analysis, is established.

Abstract:
Passive optical probes and high-resolution emission spectroscopy are used to provide a general-purpose real-time temperature and chemical species sensing capability. Probes can be inserted in the combustor, at the turbine inlet, in the augmenter, or at the engine exit with application as an engine development diagnostic tool that provides spatially resolved measurements of the key combustion parameters: temperature, CO concentration, and H2O concentration. Multiple probes are arrayed to collect the emitted infrared radiation over different views of the hot gas path. Line-of-sight averaged concentrations and temperatures are determined by spectral analysis of the emitted radiation along each line of sight (LOS). Spatial profiles may also be determined by simultaneous analysis of overlapping lines of sight. The collected infrared spectra contain optically thin and optically thick features that reflect the effects of emission and absorption within the combustion region. The known spectral structure of the component spectra can be used for the automated interpretation of the observed radiance spectra in terms of concentrations and temperatures along the line of sight, and in specific volume elements of overlapping lines of sight. In this work, we present measurements of atmospheric-pressure flames and high-pressure combustors and describe the formalism for fitting the observed spectra to a basis of simulated spectra to extract estimates of concentrations and temperatures. The spectral basis is constructed using a multilayer radiation transport model, in which each line-of-sight or measurement volume is divided into segments of uniform concentration and temperature. The observed radiance emanating from each segment is calculated as a function of the local physical variables. The collection of observed data, which contains a highly structured emission spectrum over each line of sight, is fit to the spectral basis to extract line-of-sight averaged physical properties, or in the case of spatial reconstruction, volume-averaged properties for each of the overlap regions.

Abstract:
Abstract Spectral analysis of near IR photon emissions was performed on unstrained as well as uniaxial tensile strained nMOSFETs with physical gate length of 60 nm. The significant differences in the observed spectra could be attributed to the strain-induced bandgap narrowing. This shows that photon emission spectroscopy could potentially be used as a tool to monitor strain in the nMOSFET channel.

Abstract:
Abstract Spectroscopic characterization of interconnects and circuits in semiconductor devices has become increasingly complicated as dimensions for breakthroughs and failure analysis are continuously shrinking. To achieve high spatial resolution infrared (IR) spectroscopic information, a pulsed infrared laser can be coupled to an atomic force microscope in the atomic force microscopy IR (AFM-IR) technique. The combination of AFM-IR and Lorentz contact resonance AFM (LCR-AFM) has great potential for providing high spatial resolution chemical and mechanical analysis. To demonstrate the feasibility of the AFM-based techniques, AFM-IR spectrum and images were obtained from the interlayer dielectrics of a test structure at a length scale shorter than the IR wavelength. Using the LCR-AFM technique, the relative mechanical properties of the components could be mapped distinctively by observing the contact resonance of the AFM probe. Finally, preliminary data suggest there may be AFM-IR spectral differences between contamination and the bulk material on a liquid crystal display.

Abstract:
This study describes the development and characterization of novel high-temperature thermal storage media, based on inclusion of transition metal chlorides in the potassium-sodium chloride eutectic system, (K-Na)Cl (melting temperature of 657°C, latent heat of 278 J/g). At the melting temperature of (K-Na)Cl, infrared (IR) radiation can play a major role in the overall heat transfer process — 90 percent of spectral blackbody radiation falls in the range of 2 to 13 μm. The authors propose inclusion of small amounts (less than 0.2 wt %) of IR-active transition metal chlorides to increase radiative absorption and thereby enhance heat transfer rates. A new IR reflectance apparatus was developed to allow for determination of the spectral absorption coefficient of the newly formulated PCMs in the molten state. The apparatus consisted of an alumina crucible coated at the bottom with a reflective (platinum) or absorptive (graphite) surface, a heated ceramic crucible-holder, and a combination of zinc sulfide (ZnS) and zinc selenide (ZnSe) windows for containment of the salt and allowance of inert purge gas flow. Using this apparatus, IR spectra were obtained for various transition metal chloride additives in (K-Na)Cl, and improved infrared activity and radiative transfer properties were quantified. Further, thermophysical properties relevant to thermal energy storage (i.e., melting temperature, latent heat) are measured for the pure and additive-enhanced thermal storage medium.

Abstract:
Development of the 1D and 2D IR spectroscopy of small organic molecules and clusters opens yet another way of possible identification of small organic molecules in the state of motion in the graphene nanopore scanning device. With the advantage of obtaining qualitative and at least semi-quantitative information of specimens real-time and non-invasively, vibrational spectroscopy techniques, infrared (IR) and Raman have become more and more important in the analysis of biomolecular samples. At present, the sensitivity and spatial resolution of these techniques stands at the challenge of the detection and analysis of biosamples at very low concentration (single molecule) and high spatial resolution (nanometer/sub-nanometer scale). Spectral analysis requires theoretical assignment of vibrational modes to each biomolecule. We considered vibrational spectra of DNA nucleobase at the time when they are translocated through the graphene nanopore. The Fourier transform of the density of states (DOS) of each base was calculated and the spectra of the base molecules and C atoms of graphene pore edge were obtained. Translocation rate was fixed to have maximum interaction of the base with 1.5 nm pore and single orientation of nucleobases was evaluated relative to molecular plane. Whether interaction of nucleobase and nanopore is able to enhance the signal is still remains unanswered. But we have shown that the spectra of each nucleobase are different and can be considered the fingerprint of the particular molecule. The interaction forces between pore and base are structure dependent and time-limited by translocation time. In such case, transient correlation functions were utilized for the DOSes of the individual bases and forces on each atom of the particular base were sorted by intensity. The spectra of individual atoms in the bases as well as of whole molecule were compared and frequencies of most intense peaks were related to particular atoms. Molecular dynamics method is used for the DNA base and graphene nanopore calculations with the MM2/MM3 potentials for the base and REBO graphene potential. Interaction potential between the bases can simultaneously give additional information for the electronic transport calculations with possible tra and graphene are of the MM2/MM3 part of the Van der Waals interaction only has been considered. Possibility of base identification by spectral signature is confirmed. Calculated spectra are compared with results of the existing IR measurements for nucleobases.

Abstract:
The system of programs described in this paper is concerned with estimating the damage ensuing from exposure of specimens in dry and humid atmospheres to UV and visible radiation covering the solar range. Damage is monitored quantitatively by changes in IR spectra. The dose is estimated from UV spectra of the lamps and the interference filters (used to isolate a particular wavelength range). The dosage is estimated from the dose and the UV absorption of the specimens themselves. These programs allow rapid estimation of dosage and damage from regions of data, and manipulation and processing of the massive amounts of data required to carry out such comprehensive tests in a complete yet user-friendly manner.
