Dielectric study of binary mixtures at 298K temperature


Static dielectric constants and excess properties o f three binary systems were studied at 298K tempera ture. The dielectric measurements have been carryout by using a sensor which is based on frequency domain reflec tometry technique. To determine the intermolecular interact ion and hydrogen bonding, the excess dielectric pro perties, Kirkwood correlation and Bruggeman factor of the bi nary mixtures have also been calculated and reporte d. The behavior of excess dielectric permittivity and Brug geman factor suggest the presence of molecular inte raction in the binary mixtures. The angular Kirkwood correlation f actor confirms the parallel and antiparallel orient ation of the dipoles in the binary mixtures.
