A Theoretical Study of Depolarized Rayleigh Scattering Time-Correlation Function of a Dilute Polymer Solution.

摘要

The depolarized Rayleigh spectra of macromolecules in solution have been studied theoretically. From a general expression of the time correlation function,two correlation functions respectively related to molecular rotation and local segmental motion are obtained in a natural way. Previous work has not demonstrated this connection. The result of the present analysis is valuable in the interpretation of the experimentally observed spectra of polymers in solution.
