Abstract:
Dielectric constant, dielectric loss of Pyridine and Aniline in dilute solutions in different non polar media, viz., cyclohexane, benzene and heptane at 10 GHz and at three different temperatures have been determined. Dielectric data of the solutions have been analysed to determine microscopic relaxation times (τ) and dipole moments (µ) of the systems used. Temperature dependent relaxation times of the dilute solutions and coefficient of viscosities (η) of the solvent are used in calculations of the Eyrings thermodynamic energy parameters for the activated state of the system.
Keywords: Dielectric constant, Loss, Relaxation time, Dipole moment, Thermodynamic parameters.
