The dependence of dielectric relaxation on frequency, temperature, pressure and other external factors has been used to investigate the correlation between the morphology and electrical properties of macromolecules. Study of molecular interaction of Dimethyl Sulfoxide with Ethanol has been carried out at sampling frequency 12.4 GHz and at temperatures 150C, 200C, 250C&300C. Time domain reflectometry (TDR) in reflection mode has been used as a technique. The static dielectric constant (ε0), dielectric relaxation time (τ) and thermodynamic parameters of binary mixtures were obtained from complex reflection spectra.
