Complex and thermodynamic properties of polar liquids using time domain reflectometry

Abstract

The study of complex properties in a binary mixture of 1,2-dichloroethane (DE) and n-methylformamide (NMF) polar liquids has been carried out in the frequency range of 10MHz to 30GHz for 11 different concentrations using time domain reflectometry technique at 283, 288, 293 and 298K temperatures. Complex property of binary liquids indicates the type of distribution of the dielectric relaxation time. The Bruggeman parameter gives the information about molecular interactions within binary polar liquids. Thermodynamic parameter deals with the passing of a dipole across a potential barrier which separates the minima of energy.
