What is Raman Effect?
The Raman Effect is a change in the wavelength of light that occurs when a light beam is deflected by molecules.
When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light.
Its presence is a result of the Raman effect.
