1.1.1 Physical principles

The Raman effect results from the inelastic scattering of a light beam by a medium (gas, liquid or solid). The energy difference between the incident photon of wavelength λ i and the scattered photon of wavelength λ d is exactly equal to the vibrational (or rotational) energy of the scattering molecule. Under certain conditions, this energy exchange provides access to the different vibrational...
