What is Raman Effect?

  • 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.
