Raman scattering was discovered by Sir C. V. Raman1,2 in the 1920’s. Since then Raman spectroscopy has become one of the most popular analytical techniques. It provides comprehensive information about the vibrational modes of molecules by monitoring macroscopic light scattering and has created an entire new branch of molecular spectroscopy. The Raman scattered light from the molecules, frequency shifted relative to the frequency of the light source, is generally polarized and contains information about the vibrational frequencies and anisotropy of molecular vibrations. As is well known, vibrational modes are like fingerprints of molecules. Therefore, Raman scattering is endowed with the sensitivity to discern different molecular species. Raman spectroscopy has broad applications, ranging from fundamental physical chemistry, inorganic chemistry, biochemistry, art and archaeology, to highly practical forensic examinations.
