WebThe depolarized Rayleigh light scattering spectra of pure polyethylene clycols and their solutions in an optically isotropic solvent were studied as a function of polymer molecular weight, concentration and temperature. Reorientational relaxation times were obtained by fitting the observed spectra to Lorentzian WebB. Compton and Rayleigh scatterings There are two kinds of the photon scatterings, Compton scattering and Rayleigh scattering. As shown in Fig. 5.2, a whole atom works as the target in Rayleigh scattering. When the incident photon is scattered by the atom and changes its direction, the target atom recoils to conserve
