Dielectric response of molecular interactions in liquids

Abstract

A survey was carried out concerning chosen problems of dielectric behaviour of the solute—solute-solvent interaction. Special attention was paid to the dipole moments of molecular complexes and to the solvent effect upon them. Problems of the proton density distribution in hydrogen bonded systems and the so—called superpolarizability of hydrogen bridges was discussed in the light of contemporary views. The phenomenon of the non—linear dielectric effect and anomalous positive effect in hydrogen bonded systems seemed to be of particular interest. Attention was paid to the existing conceptions dealing with this problem, namely the equilibrium model, the significant structures model, and the proton—jumping conception. Finally, an attempt was made to present a general outlook on the problem of the dynamics in solution from the point of view of dielectric relaxation in the case of forming simple molecular complexes.
