Abstract
Molecular dynamics (MD) simulations at constant temperature have been carried out for systems of 1:1 solvent primitive model (SPM) electrolyte solutions. Equilibrium thermodynamics, mean cluster size, self-diffusion coefficients, and collision frequencies were computed to examine the electrostatic effects on the structural and dynamical properties. Coherent ionic cluster motion was deduced from a cluster analysis and from the dependence of the velocity and force autocorrelation functions (FACFs). The resulting MD data for the collision frequencies and self-diffusivities of both ions and hard-spheres were shown to be in good agreement with the theoretical predictions.
