Raman Spectroscopy is a scattering technique which analyzes the scattered light of different wavelength than the incident light to obtain the molecule structure of the analyte. When a incident laser light illuminate the sample, light collide material molecules and scatter. Most of the scattered light features the same wavelength with the incident light, only a very small amount scattered light( typically 0.0000001% ) at different wavelengths with incident light, which is inelastic scatter called Raman scatter. The scattered light frequency less than incident light is called Stokes scattering, the scattered light frequency bigger than incident light is called Anti-Stokes scattering, they are symmetrically distributed on both sides of the Rayleigh scattering Details Principle Raman Spectroscopy is a scattering technique which analyzes the scattered light of different wavelength than the incident light to obtain the molecule structure of the analyte.
