Brief history：Raman effect
C. V. Raman and the Discovery of the Raman Effect
In 1928 the Indian physicist C. V. Raman (1888–1970) discovered the effect named after him.
The highest honor Raman received was the Nobel Prize in Physics for 1930 for his work on the scattering of light, particularly for his discovery of the effect named after him.

Raman Spectroscopy: Overview
Raman Spectrum
When a light monochromatic beam passes through a solid, liquid or transparent gas, near to the emission line at the same frequency of the incident light (due to the elastic scattering), one can see other emission lines of minor or major frequencies, forming the Raman Spectrum.

Striking the sample, the laser beam can give energy to the molecules that start to vibrate. In the same way, the photons can subtract a part of the vibrational energy of the molecules. So, it is possible to unambiguously identify the studied molecules.
