The Raman effect is a light scattering phenomenon. When a monochromatic incident light is scattered on a molecule or crystalline solid two types of scattering occur. The first is elastic scattering, termed as Rayleigh scattering, where there is no energy loss within the system. The second is inelastic scattering, termed Raman scattering, which involves the exchange of energy between.

Raman spectroscopy has seen tremendous growth in biological and life science applications over the past two decades. As it measures inelastic scattering from a monochromatic light source incident onto a sample, Raman spectroscopy provides rich information on molecular structures, identities, and composition, and can be used for both qualitative and quantitative chemical analysis - L'effet Raman stimulé, qui est une véritable émission laser intense, à la fréquence d'une raie vibrationnelle Raman.
