Abstract

ABSTRACT Complex permittivity spectra were measured for the binary mixtures of Ethyl Acetate (EA) with Xylene using Time Domain Dielectric Spectroscopy (TDDS) for 11 concentrations at different temperatures in the frequency range from 10 MHz to 30 GHz. The values of static dielectric permittivity and relaxation time have been obtained by fitting complex permittivity spectra using least square fit method in Debye model. The observation of excess permittivity, excess relaxation time and Kirkwood correlation factor has been undertaken to study the behaviour of molecular structure in EA and Xylene using dielectric relaxation parameters.
