Temperature Dependent Dielectric Relaxation Study of Butanenitrile with Chlorobenzene

Ishwar G. Shere

Abstract :

The complex dielectric permittivity spectra of butanenitrile(BN) with chlorobenzene(CBZ) mixture has been determined at temperature 50C in the frequency range of 10 MHz to 20 GHz using time domain reflectometry (TDR) for 11 different concentrations of the system. The dielectric parameters such as static permittivity (ε0 ) and relaxation time (τ) have been obtained by Fourier transform and the least squares fit method. The relaxation in this system can be described by a single relaxation time using the Debye model. The Excess parameters of the mixtures have been determined. In the mixtures excess permittivity is found to be negative. The excess inverse relaxation time is also found to be negative. The investigation shows that the effective dipoles of the system decreases and produces opposing field, so that dipole rotates slowly
