In the surface enhanced variety of this effect, the magnitude can be increased by the presence of small metal particles near a substance to be studied, probably due to plasmon resonance. Creating ultraviolet resonance is another technique to improve the magnitude of this effect, which is typically much weaker than the competing processes of diffuse reflectance and fluorescence. It results when an electron enters a virtual excited state, then relaxes via the emission of a photon to either a higher or lower vibrational energy level, creating the Stokes or anti-Stokes variety, respectively. FTP name this type of inelastic scattering first observed by its Indian namesake.
