Theoretical and computational studies of solvent and vibrational dynamic effects on electron transfer reactions and overtone vibrational dephasing in liquids
This thesis consists of two parts. In the first part, a detailed theoretical study of the effects of ultrafast polar solvent modes and the intramolecular vibrational modes on electron transfer reaction (E T R ) is ... -

Dynamics in complex systems: liquid crystals, biological water, supercooled water and enzymes
The origin of the glassy orientational dynamics, both single particle and collective, of nematogens near the isotropic-nematic transition has been addressed in several publications in recent years [5-7, 12]. In these ... -
Electron spectroscopic studies of the adsorption and reactivity of oxygen on transition metal surfaces covered with alkali and alkaline earth metals
Characteristic Cl(2p) and O(1s) peaks are seen by XPS attributable to distinct adsorbed chlorine and oxygen species on potassium and barium dosed Ag surfaces: a) There is selective stabilization of molecular dioxygen species ... -
Investgations of molecular interaction by photoelectron and electron energy loss spectrospies
Electronic structures of a variety of electron donor-acceptor complexes have been studied by employing ultraviolet (HeI) photoelectron spectroscopy. The systems studied are the complexes of BH? / AlCl?, GaCl? and SO? with ... -
Studies of surfaces by electron spectroscopy
All the organic molecules containing lone-pair orbitals adsorb molecularly (associatively) on copper at low temperatures (<100 K). b) It is possible to estimate the stabilization of the lone-pair orbitals due to chemisorption ... -
Theoretical studies on models for organic ferromagnetism
The thesis examines the three models in existence which predict ferromagnetism in purely organic systems. These models are (i) Mataga-Ovchinnikov model which predicts high-spin ground state in alternant polymers with ... -
Exploring Scalable Material Strategies Towards the Practical Metal-Sulfur Batteries
Lithium-ion batteries (LIBs) dominate the market of portable electronic devices and currently serve as the stand-alone power source for electric vehicles. LiBs are approaching their theoretical energy density limit, ...
