Abstract
This paper considers the relationship existing between the dielectric constant and the structure of liquids of polarizable non-polar solvents and of polarizable polar solutes. The dielectric constant depends explicitly on the local structure of the liquid through canonical media which converge over a few molecular diameters. The specific effects of the structural short ranged terms on the dielectric constant are analysed. Several liquid structures and interaction potentials are considered, leading to the conclusion that topological and energetic factors are important and that dielectric studies offer good perspectives in the field of liquid structures theories.
