Webthus, the term Raman spectroscopy almost always implies Stokes scattering rather than anti-Stokes. In CRS, however, Stokes and anti-Stokes scattering can both be readily achieved. The advantage to anti-Stokes scattering is that the gain of energy in the scattered photon equates to a blue-shift in wavelength; boils under the armpit
