New approach to relaxation data analysis in polyhydric
alcohols
Abstract
In this work, experimental data on
dielectric permittivity in the frequency range from 1 MHz to 36 GHz and in the
temperature range from 283 to 423 K for 1,3-, 1,4- and 2,3-butanediols are
analysed. Some relations between parameters of Davidson & Cole equation and
molecular structure of butanediols under consideration have been found. Mean
values of dipole moments of molecular clusters, <mc>, have been calculated in the
framework of Dissado & Hill cluster theory. Dependence of <mc> on energy parameters of this
model has been revealed and discussed.
