Molecular aspects of ionic motion 149

Instead of the movement of a proton (present in water as the H 3O species) or the OH
ion physically through solution, a concerted field-driven bond redistribution in the
hydrogen-bonded water network results in the destruction of the ion and its production in
another location. Thus, ion movement is achieved by an electronic redistribution with
little nuclear redistribution, which much enhances the transfer rate compared with other
ions.
