Investigations of intermolecular interactions between 2-methoxyethanol and nitrobenzene through dielectric relaxation study

Abstract

Complex dielectric spectra * () = i of binary mixture of 2-methoxyethanol with nitrobenzene were obtained in the frequency range of 10 MHz to 20 GHz over the volume fraction range 0 < v < 1 and at different temperatures of 288, 298, 308, and 318 K using the time domain reflectometry (TDR) technique. The static dielectric constant s and relaxation time have been obtained. These values are used to obtain the excess permittivity E s , excess inverse relaxation time (1/ ) E , Kirkwood correlation factor g eff , Bruggeman factor fB, and thermodynamic parameters. On the basis of above parameters, intermolecular interaction and dynamics of molecules at molecular level are predicated.
