Answer:

Explanation:

Raman spectra result from scattering of light by vibrating molecules whereas IR spectra result from light absorption by vibrating molecules. Raman activity results from change of polarizability of a molecule whereas IR activity results from changing dipole moment. ... Raman technique is non-destructive

RAMAN SPECTRA:

  • When a radiation  incident on a  substance, then the substance transmit the radiation which determines the raman spectra.
  • To get raman spectra, concentrated solution is used.
  • Water  can be used as solvent.
  • The samlpe tube is made up of quartz

IR SPECTRA:

  • When a radiation  incident on a  substance, then the substance absorb the radiation which determines the infra-red spectra.
  • To get infra-red spectra, dilute solution is used.
  • Water can not be used as solvent.
  • The sample tube is made up of basic metal halides.
