Biomimetic Studies on Tyrosine- and Phenolate- Based Ligands and their Metal Complexes
(2017-11-14)
Tyrosine (4-hydroxyphenylalanine) is one of the naturally occurring 22 amino acids. The importance of tyrosine is due to the presence of its phenolic side chain. In biological systems, the tyrosyl residue in proteins is ...
Synthesis of Metal and Metal Oxide Nanosponges for Hydrogen Storage and Catalytic Applications
(2017-11-28)
Nanoporous metal represents a particular form of a metal, which combines the characteristics of metals, such as good thermal and electrical conductivity, catalytic activity with the materials properties characteristic of ...
Influence of Ancillary Ligands in the Chemistry of Transition Metal σ-Complexes
(2017-09-27)
This thesis work is based on an investigation of intermediates involved in various metal mediated catalytic reactions such as hydrogenation, hydroboration, functionalization of methane etc. An intermediate dictates the ...
Organic Imine Cages : Self-Sorting and Application
(2017-11-14)
Biological systems have the incredible ability to accomplish uncommon chemical transformations with supreme delicacy. Many of those chemical transformations take place within the pocket of enzymes, which provide unique ...
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 ...
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 ...
Nature Of Solute-Solvent Interaction : Effect Of Solvent Polarity On Excited State Structure Of 2,2,2-Trifluroacetophenone And Effect Of Hydrogen Bonding In Hydrated Electron Absorption Spectrum
(2009-09-02)
In solution, the environment around the solute is determined solely by the solvent molecules, which are present closer to the solute. This interaction between solute and solvent shell is very crucial for equilibrium structure ...
