Spectroscopic studies on hydrogenases
… The second part of the thesis comprises three studies on the ReMBH. Unlike the anaerobic “standard” [NiFe]-hydrogenases, which harbour a cubane-like [4Fe4S] cluster in the proximity of the [NiFe] active site, in oxygen tolerant MBH’s, such as ReMBH, two conserved cysteines in the first …

Spectroscopic Studies of Molecular Conformations
The vibrational spectra of a series of diesters of fumaric and maleic acids and also of substituted butadienes have been investigated over a range of temperatures and phases. The effects on infrared and Raman spectra of altering the temperature and phase of these compounds (using matrix isolation …

Spectroscopic studies of magnetic cataclysmic variables
In this thesis I present the results of optical spectroscopic analyses of four Polars and the spectra of five new systems. The results of four candidate magnetic cataclysmic variables, which were selected from the ROSAT Bright Survey, are also presented. Time resolved spectra are used for the dual …

Synthesis and Spectroscopic Studies of Substituted Pyrrolocytidines
… nucleoside pyrrolocytidine. Photophysical studies were performed to determine possible FRET pairs to be used as molecular beacons and Stern-Volmer plots were used to determine how effective each quencher was at reducing the fluorescence intensity of the fluorophores. The molar absorptivity …

SPECTROSCOPIC STUDIES OF SOME AROMATIC DECOMPOSITION INTERMEDIATES
A number of aromatic radicals have been produced and identified. A re-examination has been made of spectra from discharges through toluene and toluene-alpha-d, In each case a vibrational frequency analysis has been carried out on the bands: to the violet of the (0,0) band. The fundamental …

Spectroscopic Studies of Some Semiquinone Radical Ions
Previous ESR and UV spectroscopic studies of semiquinone cations are reviewed. Cations of 4,4'-bipheno-semiquinones prepared by chemical oxidation of the corresponding diols and reduction of the quinones in sulphuric acid, were studied using ESR and UV spectroscopy. Oxidation of biphenyl-4,4'-diol …

X-ray and spectroscopic studies of organotin compounds.
… analysis have been made. Crystallographic and spectroscopic studies have been made of novel organotin compounds, allowing comparison of solid and solution phase structures to be made. Rationalisation of reactivities has also been made from the data. Crystal structures of the alpha-substituted …

Optical spectroscopic studies of two star forming regions
… and determine the star-forming history. Optical spectroscopic surveys of an unbiased sample of candidate young stars have been completed. Optical images taken in different photometric bands were used to create color-magnitude diagrams from which sources were selected for spectroscopic …

High pressure spectroscopic studies of organic device materials
… continuum. Photoluminescence and phosphorescence studies of a ladder type poly(para-phenylene) (PhLPPP) under pressure have given for the first time an evidence that the singlet-triplet splitting remains almost a constant under enhanced intermolecular interaction. For polymer bulkheterojunctions …

Magneto-optical spectroscopic studies of multi-heme enzymes
Cytochrome cd1 (cd1) is a soluble, diheme enzyme located in the periplasm of denitrifying bacteria that catalyses the one-electron reduction of nitrite ion to nitric oxide. Paracoccus pantotrophus cd1 undergoes an unusual coordinated ligand switch upon reduction to the diferrous state, whereby a …

High-resolution spectroscopic studies of carbon-containing species
High-resolution spectra of molecules and ions can provide valuable information fundamentally and astrochemically. From the fundamental side, high-resolution rovibrational spectroscopy allows molecular constants to be determined and provides evidence of theoretical assumptions. Work to this end was …

Thermodynamic and Spectroscopic Studies of Some Metal Dimers
The structure-reactivity relationships have been investigated in this study for three metal dimers including tetra-n-butyratodirhodium (II), tetra-n-butyratodiruthenium (II,III) chloride, and tetra-n-heptanatodicopper (II). These complexes were studied using a combination of calorimetry, epr …

Spectroscopic Studies of Organic Photovoltaic Non-Fullerene Acceptors
… we perform both steady-state and transient spectroscopic studies in order to advance structure-photophysics relationships for the Y-family of next-generation NFAs. We propose theoretically that the primary photoexcitation in thin films of the archetypal NFA Y6 is a manifold of hybrid …
