During recent years Raman spectroscopy seems to become a valuable analytical and research tool for analyzing molecules properties. Findings its origins in Einstein's and Planck formulation, based upon measurement of the slight wavelength shift between the stimulating photon wavelength and the inelastic scattered photon wavelength, Raman Spectroscopy is a non-destructive light scattering measurement technique, which provides extremely rich chemical and structural information of the sample.

In its simplest form, Raman spectroscopy is a non-destructive light scattering measurement technique, where a stimulating photon interacts with a sample and produces an inelastically scattered photon from the sample (where inelastic collision changes molecule energy). The existence of slight wavelength shift between the inelastically scattered photon wavelength and the stimulating photon wavelength is related to the sample molecule "finger-print" properties, and provides the chemical and structural information of the sample.
