摘要：

The dielectric relaxation of binary and ternary diol(s)/alcohol mixtures has been studied. Diols of different chain length namely 1,2 ethanediol, 1,3 propanediol, 1,4 butanediol and 1.5 pentanediol are used. The monohydric alcohols used are benzyl, n-hexyl, cyclopentyl, cyclohexyl and cycloheptyl alcohol. The relaxation spectra have been analyzed in one Cole-Davidson term. An apparent dipole moment term and the effective relaxation time of the main dispersion region are given as function or the number density of dipoles N-D.
