Molecular theory of solvated ion dynamics. II. Fluid structure and ionic mobilities

Abstract
Calculations of ionic mobility based on a molecular theory of solvated ion dynamics [J. Chem. Phys. 68, 473 (1978)] are presented. We develop approximation schemes for the equilibrium averages needed in the theory. The results for ions in water are in remarkably good agreement with experiment. The importance of fluid structure, arising from the finite size of solvent molecules, is clearly illustrated.
