In spectroscopic methods, Rayleigh and Raman scattering arise from the interaction of light with molecular vibrations. When monochromatic light interacts with a molecule, most photons are elastically scattered, meaning they retain the same energy as the incident photons. This elastic scattering produces the Rayleigh line, which corresponds to no change in the vibrational energy of the molecule. In an energy _____ _____ __________ _________ _______ __________ ______.
