Investigation of the dielectric relaxation of chlorobenzene, bromobenzene and iodobenzene

Abstract

This paper deals with the investigation results of temperature dependence of complex permittivities ε*=ε’-iε’’ of chloro, bromo and iodo – benzene at wavelength 11,50 cm and 12,80 cm within the temperature range 20 ÷ -80˚. It is established that dielectric properties of given liquids are characteristic of one relaxation time. The dielectric spectra were studied taking into account other frequencies given in the literature. In all investigated liquids, a jump appears in the real and imaginary parts of the complex permittivity at the point of the phase transition.
