The Electrostatic Contribution to Hindered Rotation in Certain Ions and Dipolar Ions in Solution. IV

Abstract

The present communication is essentially a refinement of the earlier papers of the same title. This refinement is made possible by adopting particular models to represent the shape of molecular cavities, following Kirkwood and Westheimer. An important consequence of this procedure is that the effective dielectric constants used are no longer constant, but vary with intercharge distance. It is pointed out that a more detailed treatment of the molecular shapes involved should lead to further improved calculations.
