✦ Synopsis
The establishment of the general relations between the changes of dielectric permittivity and structural and molecular-kinetic parameters is one of the important problems of physics and physical chemistry of solutions. The analysis of these relationships is carried out in present work on the basis of Fisher's idea about time-dependent structures in liquids. The general approach to instantaneous, vibrationally-averaged and diffusionally-averaged structures of liquids was formulated by I. Z. Fisher [1]. Now it is clear that a vibrationally-averaged structure in liquid can not be considered without taking into account effects of translational and rotational motions of molecules in evaluating their average centers of oscillation. A description of water structure in terms of V and V' structures [2] may be given under the following assumption about water molecules:
