Abstract
The correlation between relaxation parameters of the Cole–Davidson equation and molecular structure of liquids and processes of its realignment during thermal motion is estimated. Different ways of calculating and analyzing the dynamic properties of butanediols are considered. Dipole moments of clusters of butanediols are calculated for the first time using the Dissado–Hill cluster theory. It is shown that quantitative data on the average statistical dipole moments of clusters, correlation parameters of intracluster realignment, and the synchronous exchange of molecules between clusters can be obtained by analyzing dielectric spectra with the Dissado–Hill model. A way of calculating relaxation time depending on reciprocal temperature and using different equations is described in detail. Their correlation is shown.
