Abstract:

The vibrational spectra (3200-50 cm$ sp{-1}$ region) of the solid, mono- and disubstituted chromium(0) carbonyl complexes, Cr(CO)$ sb5$(CNBu-t) and cis-Cr(CO)$ sb4$(CNBu-t)$ sb2,$ have been recorded at selected temperatures (down to ${ sim}{40}$ K) and pressures (up to ${ sim}{40}$ kbar). The structure of Cr(CO)$ sb5$(CNBu-t) has been determined by X-ray crystallography. The solid-state splittings observed in the spectra of the two complexes are discussed in terms of their known space groups. Pressure-induced, solid-solid phase transitions were detected for both compounds by Raman and IR spect

Abstract:

Nanosecond time-resolved resonance Raman spectroscopy (ns-TR3), nanosecond transient absorption (ns-TA) and femtosecond transient absorption (fs-TA) were utilized to investigate the photochemistry of ketoprofen (KP), ketoprofen-purine dyads, fenofebric acid (FA) in different solutions. For KP, the rate constant and reaction mechanism of KP are strongly dependent on the concentration of water. In neat acetonitrile and acetonitrile-rich solutions (water:acetonitrile?1:1, v:v), KP exhibits mostly benzophenone-like photochemistry to give rise to triplet state which in turn transforms to ketyl

Abstract:

Nanosecond time-resolved resonance Raman (ns-TR3) spectroscopy was used in this thesis to study the photoreduction reactions and the photochemistry of chloro-substituted benzophenone (ClBP) triplets. The 3-chlorobenzophenone (3-ClBP), 4-chlorobenzophenone (4-ClBP) and 4,4′-dichlorobenzophenone (4,4′-diClBP) triplets exhibit similar properties to the parent BP triplet. In isopropyl alcohol (IPA), the hydrogen abstraction reactions were observed for the 3-ClBP, 4-ClBP and 4,4′-diDlBP triplets. The diphenylketyl (DPK) radicals produced from the hydrogen abstraction reactions were observed

Abstract:

The study of two pharmaceutically active systems that each display polymorphism has provided a platform upon which to develop and apply solid-state NMR techniques in order to increase the understanding of the solid-state structure of small organic molecules. The multidisciplinary approach adopted has highlighted the advantages of solid-state NMR as a non-invasive probe of molecular conformation and crystallographic packing.Carbon-13 CP/MAS spectra of the two polymorphs of BRL55834 - a fluorinated benzopyran derivative - immediately suggest the presence of one and three molecules in the asymmet

Abstract:

Ion Mobility Spectrometry coupled with Multi Capillary Columns (MCC -IMS) is a fast analytical technique working at atmospheric pressure with high sensitivity and selectivity making it suitable for the analysis of complex biological matrices. MCC-IMS analysis generates its information through a 3D spectrum with peaks, corresponding to each of the substances detected, providing quantitative and qualitative information. Sometimes peaks of different substances overlap, making the quantification of substances present in the biological matrices a difficult process. In the present work we use peak

Abstract:

The details of the interplay between the electronic structure and the magnetic properties of matter represent a state of the art challenge. In the present work spectroscopic investigations on the electronic structure of some interesting materials are presented. The achieved information has been used in order to answer specific questions related to the magnetic behavior of the investigated materials. For the transition metal dicyanamide compounds it is shown that the electronic states arising from carbon and nitrogen remain roughly unchanged for all compositions. A model for the magnetic supere
