✦ Synopsis
A recently proposed method for sohing the one-particle generalized Smohrchowski equation is used to determine the light scattering spectrum for a dilute solution of spherical, uncharged macromolecules. We fid a frequency and wave number dependent effective diffusion coefficient which offers a possible explanation for the difference in sign found for this quantity at small and large frequencies in previous work. Our results are based on the use of Oseen's model for the hydrodynamic interaction, and in this sense are considered as preliminary; an extension of these results using a higher order hydrodynamic theory is in progress.
