Abstract
Raman scattering is an optical technique that measures intrinsic properties of the molecules. Hyper-Raman scattering (HRS) is another kind of non-linear Raman scattering technique, where incident photons and scattered photons are separated by almost half of the wavelength. As scattering mechanism for RS and HRS are different, the selection rule for the two are also different, allowing HRS to show some of the vibrations that are not allowed in normal RS. Though, HRS is an important optical spectroscopic technique, it has extremely weak signal, therefore, signal enchantment is required.
