The Raman principle
The Raman effect is based on inelastic scattering of excitation light by the molecules of gaseous, liquid or solid materials. The interaction of a molecule with photons causes vibrations of its chemical bonds, leading to specific energy shifts in the scattered light that can be identified in its Raman spectrum.
Any given chemical compound produces a particular Raman spectrum when excited and can be easily identified by this individual “fingerprint.”
Raman spectroscopy is a well-established and nondestructive method for analyzing the molecular composition of a sample
