About the Speaker:

Prof.Kris Srinivasan had been Dean of Science for 20 years at Sri Sathya Sai Institute of Higher Learning(SSSIHL) after his return from Germany, Canada, Switzerland and US {close to 8 years}. He had also worked as a Senior Visiting Professor at SN Bose National Centre, Kolkata for 3 years after his retirement and was HOD, Engineering Physics, Dayananda Sagar University, Bangalore for 4 years thereafter. Currently, he is an adjunct at Amrita, Ettimadai campus. He had introduced Fiber optics and Quantum Electronics in early 1980s as special subjects for MSc Physics and at Research level at SSSIHL much ahead of IITs. He has several research publications are in Theoretical Molecular Spectroscopy, Raman Spectroscopy, Fiber Optic Sensors and devices.

Abstract of Talk: Raman Scattering

Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light’s direction. Typically this involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy.

Raman spectroscopy is used in many varied fields – any application where non-destructive, microscopic, chemical analysis and imaging is required. Whether the goal is qualitative or quantitative data, Raman analysis can provide key information easily and quickly. It can be used to rapidly characterise the chemical composition and structure of a sample, whether solid, liquid, gas, gel, slurry or powder.

Some of its applications are: Pharmaceuticals and Cosmetics, Geology and Mineralogy, Semiconductors, etc.
