Dielectric relaxation in 1,1,1-trichloroethane/cyclohexane solutions

Abstract

Complex dielectric permittivity measurements on liquid 1,1,1-trichloroethane and cyclohexane and several mixtures of these liquids are reported at centimeter and millimeter wavelengths and 25 °C. It appeared possible to discriminate, with the reported permittivity measurements and the correlation functions given by Nee and Zwanzig and by Lobo et al., the models of dielectric relaxation proposed by Glarum and Cole and by Nee and Zwanzig in favor of the latter. The theories of dielectric relaxation in polar liquids of Nee and Zwanzig and of Lobo et al. are extended to solutions and in particular to binary mixtures of polar and nonpolar liquids.
