Rayleigh scattering study of selected polymers

摘要

The Rayleigh scattering spectra of polyethyleneglycols with different average molecular weight are presented. In the study we used the compounds with average molecular weight 1500 and 2000. The temperature and concentration dependencies of the Rayleigh scattering spectra have given the possibility to determine Rayleigh parameters, also isotropy and anisotropy scattering molecular factors.
