Rotational Specroscopic And Theoretical Investigations Of Non-conventional Hydrogen Bonds
(2014-11-12)
The nature of interactions within a molecule, i.e. chemical bonding, is well understood today. However, our understanding about intermolecular interactions, which has great relevance in nature, is still evolving. Historically ...
Electronic and Magnetic Structures of Some Selected Strongly Correlated Systems
(2018-01-04)
Transition metal oxides and chalcogenides are an ideal platform for demonstrating and investigating many interesting electronic phases of matter. These phases emerge as a result of collective many body interactions among ...
Ultrafast Raman Loss Spectroscopy (URLS) : Understanding Resonant Excitation Response And Linewidth Changes
(2016-02-25)
Raman spectroscopy involves change in the polarizability of the molecular system on excitation and is based on scattering process. Spontaneous Raman scattering is a two photon process, in which the input light initiates ...
Understanding Solvent Effect On Triplet State Structure Of Thioxanthone And Its Derivatives Using Time-Resolved Resonance Raman Spectroscopy
(2014-05-01)
It has long been recognized that course and efficiency of a chemical reaction is largely mediated by the short-lived transient species (excited state or radicals) which are formed as reactive intermediates during a chemical ...
Ultrafast Raman Loss Spectroscopy (URLS)
(2015-02-05)
Contemporary laser research involves the development of spectroscopic techniques to understand the microscopic structural aspects of a simple molecular system in chemical and materials to more complex biological systems ...
Probing The Equilibrium Geometry Of Weakly Interacting Systems In Solution By Hyper-Rayleigh Scattering
(2014-08-11)
Under the electric dipole approximation, second harmonic of the incident light is scattered by a collection of randomly oriented molecular dipoles in solution due to instantaneous orientational fluctuation which is ...
Exploring Diverse Facets of Small Molecules by NMR Spectroscopy
(2017-12-07)
The thesis entitled “Exploring Diverse Facets of Small Molecules by NMR Spectroscopy” consists of six chapters.
The main theme of the thesis is to exploit one and two dimensional NMR methodologies for understanding the ...
Phase Transition In Soft-Condensed Matter Fluids And Contribution To Enzyme Kinetics Including Kinetic Proofreading
(2016-11-16)
The thesis involves computer simulation and theoretical studies of phase transition in soft-condensed matter systems and theoretical understanding of enzyme kinetics along with kinetic proofreading of tRNA-aminoacylation ...
Crystal Engineering : From Molecule To Crystal Structure Landscape
(2017-08-21)
Crystal engineering underlies the essence of natural affiliation between the molecule on the one side and the crystal as a supramolecular assembly on the other. Molecular recognition is the fundamental cause for this ...
Exploring Transition Metal Oxides Towards Development of New Functional Materials : Lithium-ion Battery Cathodes, Inorganic Pigments And Frustrated Magnetic Perovskite Oxides
(2017-10-11)
Transition metals (TMs) are ‘elements whose atoms have partially filled d-shell, or which can give rise to cations with an incomplete d-shell’. In TMs, the d-shell overlaps with next higher s-shell. Most of the TMs exhibit ...
