The Molecular Correlation of 2-Pentenenitrile and Chlorobenzene Mixture at 15oC Temperature

I. G. Shere

The dielectric study of 2-pentenenitrile (PN) with chlorobenzene (CBZ) mixture has been carried out at temperature 150C 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 dielectric constant (ε0) and relaxation time (τ) have been obtained by Fourier transform and the least squares fit method and these are fitted in Kirkwood model. The Kirkwood correlation factor (gf) and effective Kirkwood correlation factor (geff ) of the mixtures have been determined. In the mixtures the values of geff are less than one and it shows that; the antiparallel alignment of dipoles and the values of gf are less deviated from one it represents that; weaker interaction between the constituent molecules of the system.
