Raman Spectroscopy Basics
Page 1 of 5 Raman the FutureIntroductionRaman Spectroscopy is a spectroscopic technique based on inelastic scattering of monochromatic light, usually from alaser source. Inelastic scattering means that the frequency of photons in monochromatic light changes upon interactionwith a sample. Photons of the laser light are absorbed by the sample and then reemitted. Frequency of the reemittedphotons is shifted up or down in comparison with original monochromatic frequency, which is called the Raman shift provides information about vibrational, rotational and other low frequency transitions in molecules. Ramanspectroscopy can be used to study solid, liquid and gaseous Origins of RamanThe Raman effect is based on molecular deformations in electric field E determined by molecular polarizability . The laserbeam can be considered as an oscillating electromagnetic wave with electrical vector E.
