WebSep 7, 2010 · In the Rayleigh region, the scattering function is symmetric ( μ = 0). For randomly polarized incident radiation, we have the following expression for the scattering function: (3) and polarization degree is given by the formula. (4) so that scattered radiation is totally polarized in direction μ = 0 (σ = π/2). WebRaman scattering,commonly referred to as the Raman effect, is a two-photon event involving a change in polarizability of the molecule with respect to its vibrational motion in the form of scattered energy.. When light from a laser (single frequency) contacts a sample, it changes the polarization of the molecule's electron cloud, leaving the molecule in a temporary, …
