Materials Chemistry in Search of Energy Materials : Photovoltaics and Photoluminescence
(2017-11-28)
One third of world’s total energy is used in production of electricity and one fifth of the total electricity produced in the world is used in lighting. Hence, the materials that have high potential in the field of ...
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 ...
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 ...
