Collective density fluctuations and dynamics of ions in water studied by the interaction-site model of liquids
The collective excitations in water are studied based on the interactionsite model of liquids. Three collective modes, extracted from a generalized Langevin equation combined with the RISM theory of liquids, are identified as an acoustic mode and two optical modes. The drag force exerted on ions...

| description |
The collective excitations in water are studied based on the interactionsite
model of liquids. Three collective modes, extracted from a generalized
Langevin equation combined with the RISM theory of liquids, are identified
as an acoustic mode and two optical modes. The drag force exerted on ions
in water is described in terms of the response of these solvent collective
excitations to the perturbation of ions. The ion-size dependence of the drag
force, which has been a central issue in physical chemistry for long time, is
studied in molecular detail based on the novel approach. |
