Question

what is raman effect

Answer 1

Raman effect is the inelastic scattering of a photon.For the discovery of Raman effect, Raman was awarded the Nobel Prize in Physics in 1930.According to this effect,when light is scattered by the particles of medium then there is a change in frequency and wavelength of the scattered wave.It is right to say that the line spectrum of the scattered light will have one prominent line corresponding to the original wavelength of the incident radiation. Also additional lines appear each side of it corresponding to the shorter or longer wavelengths of the scattered light. This Raman spectrum is characteristic of the transmitting substance. Raman spectrometry is a useful technique in the characterization of materials.
