Raman Spectroscopy


Raman spectroscopy is a non-destructive vibrational spectroscopy technique to identify a fingerprint of a material based on vibrational frequencies of the various atomic bonds in the material.

Raman spectroscopy is a complementary technique to IR absorption spectroscopy, but provides a plethora of information about the samples other than identification. Raman spectroscopy can be used with solid, liquid and gaseous samples. Raman spectroscopy facility in MSE@IITK includes three lasers (532nm, 633nm and 785 nm) and a heating/cooling stage for samples. The spectrometer range is from 50 to 4000 cm-1 (Raman shift) and max resolution of 0.5 cm-1. Raman spectroscopy can be utilized for identification of materials (chemical bonds), phase (symmetry), calculation of stress (change in bond lengths) and probing of electronic structure of nanomaterials.
