Principle of Raman

When light is incident on a substance, elastic scattering and inelastic scattering occur. The scattered light in elastic scattering has the same wavelength as the incident light. In inelastic scattering, the scattered light has components with wavelengths longer and shorter than that of the incident light, collectively known as the Raman effect. The Raman effect is the result of the interaction between photons and optical phonons.

Raman Spectroscopy - Principle The Raman effect originates from molecular vibrations (and lattice vibrations) and rotations. Therefore, information about the vibrational energy levels (lattice vibrational energy levels) and rotational energy level structures of molecules can be obtained from Raman spectra. The concept of a virtual upper energy level can explain the Raman effect.
