Abstract:
NASA's Stardust mission flew through the coma of comet Wild 2 in January 2004, capturing dust grains as it did so. The grains were returned safely to Earth in January 2006, and are in the process of being distributed to investigators. As members of the Spectroscopy Preliminary Examination Team, we are preparing to analyse Stardust grains. Our contribution is to measure the spectrum of the grains between 200 nm (in the near ultraviolet) and 800 nm (near infrared). The purpose of the measurement is to provide an additional technique for characterizing the grains, one that is complementary to other spectroscopic techniques and one that produces results that can be matched directly with spectra acquired remotely (with telescope or spacecraft instrumentation). As part of the preparation for analysis of Stardust materials, we are producing a database of spectra from appropriate minerals, and are honing the technique through analysis of primitive meteorites.

Abstract:
We present a review of UV observations of massive stars and their analysis. We discuss O stars, luminous blue variables, and Wolf–Rayet stars. Because of their effective temperature, the UV (912−3200 Å) provides invaluable diagnostics not available at other wavebands. Enormous progress has been made in interpreting and analysing UV data, but much work remains. To facilitate the review, we provide a brief discussion on the structure of stellar winds, and on the different techniques used to model and interpret UV spectra. We discuss several important results that have arisen from UV studies including weak-wind stars and the importance of clumping and porosity. We also discuss errors in determining wind terminal velocities and mass-loss rates.

Abstract:
This thesis examines the performance of a custom built deep UV laser (257.5nm) for Raman spectroscopy and the advantages of Raman spectroscopy with a laser in the deep UV over a laser in the visible range (532 nm). It describes the theory of resonance Raman scattering, the experimental setup for Raman spectroscopy and a few Raman spectroscopy measurements. The measurements were performed on biological samples oak tree leaf and lactobacillus acidophilus and bifidobacteria from probotioc medicinal capsules. Fluorescence free Raman spectra were acquired for the two samples with 257.5 nm laser. The Raman spectra for the two samples with a 532nm laser was masked with fluorescence. Raman measurements for an inorganic salt sodium nitrate showed a resonance Raman effect with 257.5 nm laser which led to enhancement in the Raman intensity as compared to that with 532 nm laser. Therefore we were able to demonstrate two advantages of deep UV Raman spectroscopy. First one is the possibility of acquiring fluorescence free spectra for biological samples. Second is the possibility of gaining enhancement in Raman intensity due to resonance Raman effect. It was observed that 257.5 nm laser requires optimization to reduce the bandwidth of the laser to get better resolution. The 257.5 nm laser also needs to be optimized to obtain higher power to get better signal to noise ratio. The experimental setup can also be further improved to obtain better resolution. If the improvements required in the setup are implemented, the deep UV Raman setup will become an important tool for spectroscopy.

Abstract:
Biological macromolecules are becoming increasingly important as a target for pharmaceutical research. Structural examination of this class of compounds is vital, both in terms of understanding the three-dimensional structures these molecules form as well as for quality control of bio-pharmaceutical products. UV polarised spectroscopy, such as circular dichroism (CD) is a powerful tool for this form of analysis, rapidly providing the user with structural information on the sample. The ease of data analysis combined with its non-destructive nature make UV polarised spectroscopy an ideal tool for this purpose. However, limitations in the current instrumentation, especially in terms of sample handling have placed significant barriers in the way of fully realising the potential of these techniques. To address the weaknesses of the currently available UV polarised spectroscopy accessories, new devices have been designed and tested to increase the utility of such techniques. A low volume capillary sample holder has been developed which significantly reduces the sample requirements for circular dichroism without loss of signal quality. This advance has been coupled with an HPLC auto-sampler to create a device that can process 96-well and in some cases 384- well plates. This device opens up a host of new applications for polarised UV spectroscopy, including refolding screening as well as freeing up user time. Additionally, a high precision demountable micro scale cuvette has been developed that reproducibly assembles to the same path length every time. The percentage error of path-length for this new cuvette is of the same order as currently commercially available 1 mm cuvettes. This new accessory should prove highly advantageous for the bio-pharmaceutical industry, as it allows accurate path-length CD analysis for high concentration samples. Additionally, the first confirmed linear dichroism (LD) spectrum of a bacterium and flagella are reported, opening up the potential for real time UV spectroscopic analysis of living bacteria. By using the work contained within this thesis, it should be possible to construct a new form of high path-length accuracy, low volume, multiple-sample UV polarised spectroscopy accessory that could be used for both CD and LD analysis.

Abstract:
The UV adsorption and photodissociation dynamics have been extensively studied by spectroscopic analysis of both the atomic and diatomic photofragments. Central to the study is the UV absorption which consists of the extremely intense Hartley band (200 - 310nm) and the less intense structured tail to lower energy called the Huggins bands (310 - 360 nm). The dissociation channels along with their thermodynamic thresholds for the dissociation of vibrationally relaxed ground state ozone are as follows: (A) O3 + hn (r) O(3PJ) + O2 (X 3 S-g) (1178 nm) (B) (r) O(3PJ) + O2 (a 1 Dg) (612 nm) (C) (r) O(3PJ) + O2 (b 1 S+g) (463 nm) (D) (r) O(1D) + O2 (X 3 S-g) (411 nm) (E) (r) O(1D) + O2 (a 1 Dg) (310 nm) The contribution of the spin-forbidden channels to Huggins band photodissociation was quantified using Resonance Enhanced Multiphoton Ionisation (REMPI) detection of the O (3P0) fragments combined with a delayed pulsed field extraction technique. The translational angular properties of the photofragments were measured as part of this technique. The observed trimodal velocity distribution of the O (3 P0) fragments was suggested to be a result of the different amounts of internal energy taken from the dissociation event by the diatomic co-fragments of channels (A), (B) and (C). However, a bimodal vibrational distribution of one of the channels could not be excluded at this stage as the slowest velocity peak of the O (3P0) fragments may be due to formation of high vibrational levels of the diatomic fragments of channels (A) or (B). REMPI spectroscopy was used to detect the diatomic photofragments in a rotationally and vibrationally selective manner. In these experiments ozone was photolysed with tunable UV radiation and the fragments were state selectivity ionised using (2 + 1) REMPI via the O2 (d 3ssg 1IIg) state using a second probe laser. This Rydberg state was found to be heavily perturbed by nearby valence state, yet it was possible to identify O2 (b 1 S+g, v = 0) fragments produced via spin-forbidden dissociation from a singlet state of ozone excited by absorption in the Huggins band region.

Abstract:
Le nitrure de bore hexagonal (h-BN) est un semi-conducteur à large bande interdite (~ 6 eV) avec une stabilité thermique et chimique très élevées lui offrant la possibilité d'être utilisé dans des dispositifs fonctionnant dans des conditions de fonctionnements extrêmes. La nature indirecte de la bande interdite dans h-BN a été étudiée à la fois par des calculs théoriques et par des expériences. Un exciton indirect et des recombinaisons assistées par phonons dans h-BN ont été observées par photoluminescence.Durant cette thèse, nous avons étudié les propriétés optiques de cristaux massifs et de couches hétéro-épitaxiales de nitrure de bore hexagonal. Nous avons étudié des échantillons provenant de différentes sources et des cristaux qui ont été fabriqués en utilisant différentes méthodes de croissance pour nous permettre de mesurer les propriétés optiques intrinsèques de h-BN. Nous rapportons l'impact des symétries des phonons sur la réponse optique du h-BN en effectuant des mesures photoluminescence résolues par polarisation. L’analyse des données en polarisation, nous permet de mesurer la contribution du phonon manquant, celui qui n'a pas été détectée avant cette thèse. En suite, nous démontrons que l'origine de la structure fine du spectre de PL provient pour chaque réplique phonon d’une diffusion complémentaire de type Raman faisant intervenir le mode de phonon E2g à basse énergie (mode de cisaillement inter-feuillets). Les spectroscopies de photoluminescence et de diffusion inélastique Raman ont été combinées pour quantifier l'influence des effets isotopiques sur les propriétés optiques de h-BN ainsi pour révéler que les modifications des interactions de van de Waals liées à l'utilisation de 10B et 11B ou du bore naturel pour la croissance de cristaux h-BN massifs.Enfin, nous étudions des epitaxis de h-BN crues par Épitaxie sous Jets Moléculaires. L'utilisation conjointe de l’imagerie par microscopie à force atomique (AFM) et de la spectroscopie de photoluminescence permet de comprendre la première observation de recombinaison assistée par phonons dans des épitaxies de h-BN sur le saphir et le graphite. Ce résultat indique que la croissance de h-BN à large échelle par méthode épitaxiales est en voie d'acquérir la maturité nécessaire au développement technologique de h-BN
Hexagonal boron nitride (h-BN) is a wide bandgap (~ 6 eV) semiconductor with a very high thermal and chemical stability often used in devices operating under extreme conditions. The indirect nature of the bandgap in h-BN is investigated by both theoretical calculations and experiments. An indirect excion and phonon-assisted reombinations in h-BN are observed in photoluminescene spectroscopy.This thesis focus on the optical properties of bulk and epilayers of h-BN. We investigated samples from different sources grown different methods in order to confirm the intrinsic optical properties of h-BN. We report the impact of the phonon symmetry on the optical response of h-BN by performing polarization-resolved PL measurements. From them, we will measure the contribution of all the phonon-assisted recombination which was not detected before this thesis. We follow by addressing the origin of the fine structure of the phonon-assisted recombinations in h-BN. It arises from overtones involving up to six low-energy interlayer shear phonon modes, with a characteristic energy of about 6.8 meV.Raman and photoluminescence measurements are recorded to quantify the influence of isotope effects on optical properties of h-BN as well as the modifications of van de Waals interactions linked to utilization of 10B and 11B or natural Boron for the growth of bulk h-BN crystals.Finally, we study h-BN thin epilayers grown by Molecular Beam Epitaxy at Nottingham University, atomic force microscopy (AFM) images and photoluminescence features are combined to confirm the first observation of phonon-assisted recombination in high quality thin h-BN epilayers grown on c-plane sapphire and Highly Ordered Pyrolitic Graphite. This demontrates that large scale growth of h-BN by epitaxy is getting a technologically required maturity

Abstract:
Ces dernières décennies, des champs magnétiques ont été détectés dans quasiment tous les types d'étoiles. Ces découvertes ont donné lieu à des études innovantes sur la cartographie des champs magnétiques et leur impact sur l'environnement stellaire. Pour aller encore plus loin il est nécessaire d'allier la spectroscopie à la polarimétrie, dans l'UV et le visible. L'UV permet d'étudier les vents stellaires et l'environnement circumstellaire, tandis que le visible permet d'étudier la surface de l'étoile. La spectropolarimétrie UV+visible permet ainsi d'étudier les magnétosphères dans leur globalité. Ceci doit être fait sur au moins une période complète de rotation de l'étoile. Pour cela, il faut aller dans l'espace, à la fois pour atteindre le domaine UV et pour obtenir des observations ininterrompues sur une période de rotation stellaire complète. Le consortium international UVMag a été créé en 2010 pour discuter, étudier et promouvoir une mission spatiale pour l'étude des magnétosphères stellaires via de la spectropolarimétrie spatiale dans les domaines UV et visible simultanés. D'un point de vue technique, la spectroscopie spatiale pure, y compris dans l'UV, a déjà été utilisée avec succès, par exemple sur IUE, et serait très performante avec les détecteurs et les technologies disponibles aujourd'hui. Par contre, le spectropolarimètre UV+visible est la partie instrumentale la plus ambitieuse pour une future mission spatiale. En effet, alors que les français (en particulier le LESIA et l'IRAP) sont les spécialistes de ce type de spectropolarimètres dans le visible pour des télescopes au sol (comme ESPaDOnS au CFHT ou Narval au TBL), aucun instrument de ce type n'a encore été embarqué sur une mission spatiale, encore moins en UV. La première partie de ma thèse consistait à concevoir le design optique du module polarimétrique pour le spectropolarimètre de la mission Arago, dans le cadre du consortium UVMag. J'ai donc étudié et recherché différents concepts innovants qui pourraient s'adapter aux contraintes très particulières de cet instrument. En effet, les spécifications imposent l'utilisation d'un unique polarimètre pour tout le domaine spectral [119-888] nm. Les contraintes du spatial s'ajoutent à cela avec un besoin de compacité, légèreté et robustesse. Je me suis concentré sur 2 concepts de polarimètre différents, un premier basé sur le module de polarisation de l'instrument X-Shooter avec une modulation temporelle de la polarisation et une achromatisation des efficacités d'extraction des paramètres de Stokes et un second basé sur une modulation spatiale de la polarisation, permettant d'obtenir un polarimètre statique. J'ai adapté ces 2 concepts aux spécificités d'Arago et intégré ces 2 systèmes au design optique global de l'instrument. Le premier concept de modulation temporelle a été choisi pour l'instrument d'Arago qui a été soumis à l'ESA dans le cadre des appels Cosmic Vision M4 et M5. Dans un deuxième temps, l'objectif de ma thèse était de prouver la faisabilité des concepts évoqués plus haut
Over the last few decades, magnetic fields have been detected in almost all kinds of stars. This led to innovative studies on the mapping of magnetic fields and their impact on the circumstellar environment. To go further, we need to use spectroscopy and polarimetry together, in the UV and visible range. The UV domain is used to study the stellar wind and stellar environment, whereas the visible range allows to study the surface of the star. UV+visible spectropolarimetry enables the global study of magnetospheres. This has to be done over at least one rotation period of the star. Therefore, we need to go to space in order to see the UV range and to obtain uninterrupted observations on a complete stellar rotation period. The international consortium UVMag has been created in 2010 to discuss, study and promote a space mission for the study of stellar magnetospheres using simultaneous UV and visible space spectropolarimetry. From the technical point of view, pure spectroscopy in space, both in the UV and visible ranges, has already been successfully used, for example on IUE, and would be very efficient with current detectors and technologies. On the other hand, the UV+visible spectropolarimeter is the most ambitious instrumental challenge for a future space mission. Indeed, until now, no such optical spectropolarimeter has flown on a space mission, despite the fact that the French (particularly the LESIA and IRAP laboratories) are the specialists for such instruments (such as ESPaDOnS at CFHT or Narval at TBL). The first part of my thesis consisted in elaborating the optical design of the polarimetric module for the spectropolarimeter of the space mission Arago, in the framework of the UVMag consortium. I studied various innovative concepts that could be adapted to the specific constraints of this instrument. The specifications indeed show the need for a unique polarimeter covering the complete spectral range [119-888] nm. Moreover, the usual compacity, lightness and robustness constraints of a space instrument are added to these specifications. I focused my work on 2 different polarimeter concepts, a first one based on the polarimetric module of the X-shooter instrument using a temporal modulation and an achromatization of the extraction efficiencies of the Stokes parameters, and a second one based on spatial modulation of the polarization, offering a static polarimeter. I adapted these 2 concepts to the specific constraints of Arago and integrated them to the complete optical design of the instrument. The first concept, using temporal modulation, has been chosen as the baseline for the instrument proposed to ESA for the Cosmic Vision calls M4 and M5. The goal was then to demonstrate the feasibility of the two concepts

Abstract:
This dissertation focusses on some advancements in methodology for measuring and analysing dissolved organic carbon (DOC): analysing data from a high resolution sensor generating DOC concentrations, [DOC] and secondly the use of Raman spectroscopy to analyse the composition of DOC. Recent advances in sensor technology have enabled the collection of DOC data with greater frequency over extended time periods than was previously possible through manually collecting water samples. In this research a time series of 30 minute [DOC] data for 2.5 years from Drumtee water, a peaty catchment in Scotland, was generated and analysed using a Spectro::lyserTM from S::CanTM, with a customised algorithm for calculating [DOC]. The time series revealed details of events and strong seasonal variation in the [DOC], with a range of 8.0 mg/l to 55.7 mg/l. During the same time period measurements made using manual sampling of river water were very similar, ranging from 10.2 mg/l to 81.1 mg/l (with the second largest value at 64.1 mg/l). Similar DOC export budgets were calculated from Spectro::lyserTM measurements and from the laboratory-analysed samples for both the hydrological year 2012/13 (HY 2012/13) and hydrological year 2013/14 (HY 2013/14). For the HY 2012/13 year the DOC budgets using the field collected data and the laboratory collected data were 16.6 gCm2.yr-1 and 19.8 gCm2.yr-1 respectively. For the HY 2013/14 year the DOC budgets using the field collected data and the laboratory collected data were 18.1 gCm2.yr-1 and 19.5 gCm2.yr-1 respectively. The similarity between the budgets calculated using the high-resolution [DOC] sensor and the budget calculated using laboratory measured [DOC] samples indicated that seasonal variation had a greater influence on export budgets than short term events had. GAMs were used to model the high resolution [DOC] data, and the model generated an R2 value of 0.75 and a p-value of < 2.2 x 10-16. It was also identified statistically that there were regular [DOC] dilutions during events and that these dilutions tended to coincide with the time period when discharge was increasing most rapidly. To identify relationships and periodicities in the high resolution [DOC] time series that would otherwise be challenging to identify three forms of wavelet analysis were used. These were continuous wavelet transforms (CWTs), maximal overlap discrete wavelet transforms (MODWTs) and wavelet coherence transforms (WTCs). Using the WTCs, it was determined that there were short term correlations between the [DOC] and pH between 25 June 2013 and 17 July 2013, between [DOC] and SC during 7 August 2013 and 7 October 2013 and between [DOC] and water temperature during 19 June 2013 and 30 June 2013. Although the although the relationship between [DOC] and temperature is strong over a full year it was over these shorter time periods the weakest of the three relationships established. Identifying this coherence was not possible using bivariate analysis and the long periods of no coherence obscured these responses when analysing the data on scatter plots. Although wavelet analysis has been used in other applications this is one of the first instances in which this technique has been applied to [DOC] time series. Raman spectroscopy, conducted using a 785 nm laser, was explored as an analytical tool that could enable a better understanding of DOC composition, as an alternative to the use of fluorescence spectroscopy. Tests were conducted using both Stokes and anti-Stokes Raman spectroscopy measurements with the best results obtained using anti-Stokes Raman spectroscopy. Solid phase measurements were made of glucose, fructose, sucrose, glycine, tyrosine, tryptophan and phenylalanine, but only the glucose produced a measurable spectrum of these substances. Measurements (powders and solutions) were made of humic and fulvic acids and these produced spectra that were measurably different from the background signals. The limit of detection was measured to be approximately 500 mg/l for both the humic acid and fulvic acid. It was identified that comparing the sections of the measured spectra between wavenumbers -1100 cm-1 to -1400 cm-1 to -1800 cm-1 to -2000 cm-1 could be used to differentiate between humic and fulvic acids. In summary, this research has focussed on the use of use high resolution sensor technology to generate and then analyse a long time series in a fluvial system with a particularly high [DOC], and made advances in being able to model the [DOC] using a GAM model, despite the complex relationship measured between discharge and [DOC]. Additionally, wavelet analysis has been applied to a [DOC] data set to identify trends in the [DOC] time series that would otherwise be hard to identify. Wavelet analysis has been applied to other geophysical time series such as those found in atmospheric research, but this appears to be the first time it has been applied to [DOC]. Additionally, the use of the anti-Stokes region of the Raman spectra has allowed identification of humic and fulvic acids, and established a limit of detection. Furthermore, an absorbance ratio was identified that can be used to determine whether a solution of humic substances is dominated primarily by humic acid or fulvic acid. This research appears to be the first study to explore this.

Full text
Abstract:
At the 1995 FTS topical meeting, our group presented a description of issues surrounding calibration of the wavenumber scale of our Chelsea Instruments UV/visible FTS.1 Inconsistencies observed when using wavelength standards from Ar II2 and 198Hg3 formed a large part of that discussion. We have continued to work on this problem, with the intent of resolving these discrepancies and probing the limits of precision of the wavenumber scale in FTS.

Full text
Abstract:
Much effort over many years has gone into evaluating and improving the wavenumber accuracy of FTS - the x-axis - but relatively little attention has been paid to the accuracy of the intensity measurements - the y-axis. This is particularly true of the UV region, where almost all spectrophotometry is done with grating instruments. We have used our high resolution UV FT spectrometer for making three different types of intensity measurements: branching ratios in emission, absorption cross-sections, and (at low resolution) lamp calibration. In the course of these measurements we have identified a number of sources of potential error, some known in advance and some discovered the hard way, some common to grating and FT spectrometers and some peculiar to FTS, and some that particularly affect the short wavelength region. This paper discusses the principal problems and the lessons we have learned. It also indicates some of the advantages (and the occasional disadvantage) that FTS has over grating spectrometry for radiometry in the UV.

Full text
Abstract:
Wavelength accuracy is a key characteristic of FTS, and impressive results are available with relative ease. Assuming adequate signal-to-noise ratio, wavelength uncertainty arises from two primary phenomena — the effect of using a finite size aperture (and photon detector), and from cosine errors arising from imperfect alignment of the sample and reference beams. These effects are typically small enough to ensure uncalibrated accuracy of about 1 part in 105. Significant improvement can be attained through a single point, multiplicative calibration approach, which has been reported to reduce uncertainties to several parts in 108. In fact, relative line positions for strong lines within a given spectrum can be determined with a precision of several parts in 109. [1]

Full text
Abstract:
In the region 250-175 nm the penetration of solar radiation into the atmosphere is controlled by the absorption cross sections of O2 bands. Part of the radiation transmitted in this vacuum ultraviolet wavelength region is available to photodissociate minor species including NO. The molecular absorption processes and parameters related to the absorption of ultraviolet solar radiation in the terrestrial middle atmosphere have been discussed by a number of authors. For accurate modelling of this important process, the computations involving O2 and minor species must be performed on a line-by-line basis; laboratory-measured photoabsorption cross sections, with resolution sufficient to yield true cross sections (i.e. undegraded by instrumental effects), are required for both molecules. For most of the Schumann-Runge (S-R) bands of 16O2 and its important isotopic variants, such measurements have been successfully completed [Yoshino et al. , 1983; 1987; 1990].
