Dispersion Self-Free Energies and Interaction Free Energies of Finite-Sized Ions in Salt Solutions

Bostrom, Mathias Anders; Ninham, Barry


The role for many-body dipolar (dispersion) potentials in ion-solvent and ion-solvent-interface interactions is explored. Such many-body potentials, accessible in principle from measured dielectric data, are necessary in accounting for Hofmeister specific ion effects. Dispersion self-energy is the quantum electrodynamic analogue of the Born electrostatic self-energy of an ion. We here describe calculations of dispersion self-free energies of four different anions (OH-, Cl-, Br-, and I-) that...[Show more]
