Study on the crossover of static dielectric constants of liquids with temperature and the relevant correlations

Abstract

In order to induce the general behaviors of the orientation correlations between molecules from the variation of static dielectric constant of liquid with temperature, we filtrate the experimental data of 18 kinds of liquids with the contribution of the electronic polarizations much smaller than that of the orientation correlations between molecules from the present references. The results indicate that there is a universal crossover for the varication of the static dielectric constants of the liquids with temperature, and for such a kind of crossover, there exist at least two kinds of orientation correlation orders between molecules, one increases but the other decreases with temperature.
