Structure of Polyelectrolyte Solutions

Abstract
We present a liquid-state theory for polyelectrolyte solutions. The theory predicts liquidlike structure on long length scales in dilute solution which disappears in semidilute solutions. The predictions of the theory for the static structure factor in tobacco mosaic virus solutions are in good agreement with light-scattering experiments in both dilute and semidilute solutions. Predictions for the scaling of the position of the maximum in the structure factor with concentration are consistent with experiments.
