Light Scattering from Polydisperse Rods and Gaussian Coils. I. Integrated Intensities

Abstract

Calculations of the effect of polydispersity on the integrated intensities of the various contributions to the spectral distribution of light scattered from infinitely dilute solutions of rigid‐rod and Gaussian‐coil macromolecules have been performed using Schulz's molecular size distribution. It is shown that rotational (or in the Gaussian‐coil case—intramolecular) contributions become more important at lower scattering parameter values as the molecular size distribution becomes broader. Tables of the integrated intensities are given.
