Unformatted text preview: The light loses energy to the material in an amount equal to the vibrational energy of the molecules is the sample. This lose of energy shows up in the scattered light as a new down shifted frequency from that of the original input light frequency. Unlike IR absorption which is based on the electric dipole, Raman scattering is based on the polarizability of the molecule Roughly speaking the polarizability of a molecule determines how the electron density is distorted through interaction with an electromagnetic eld. 233...
