Total Intensity Light Scattering from Solutions of Macromolecules

Abstract

The analysis of total intensity light scattering from solutions of macromolecules is discussed, covering the concentration range from infinite dilution to concentrated solutions, with a few examples for the scattering from colloidal dispersions of particles and micelles. The dependence on scattering angle is included over this entire range. Most of the discussion is limited to the Rayleigh-Gans-Debye scattering regime, but Mie scattering from large spheres is also discussed. Examples include the effects of heterogeneity of molecular weight and chemical composition, optically anisotropic chain elements, deviations from flexible chain conformational statistics and intermolecular association.
