Potential of mean force on an ion near a wall in presence of a molecular solvent
Résumé
The potential of mean force is calculated for one ion immersed in a fluid of dipolar hard spheres in the vicinity of a neutral hard wall. The molecular nature of the solvent induces significant deviations from the primitive model result. A pure MSA treatment would only give the potential of mean force associated with the hard sphere fluid. The present theory automatically includes the existence of the image potential.
