Dielectric permittivity and relaxation dynamics of binary and ternary mixture of stearic acid on various concentration and their thermodynamic effects are studied. The static dielectric constant (" 0 ), dielectric permittivity (" 0 ) and dielectric loss (" 00 ) are found by bilinear calibration. The relaxation time (), dielectric strength (Á") and the excess permittivity (" E ) are found. The thermodynamic parameters such as enthalpy (ÁH), entropy (ÁS) and Gibb's free energy (ÁG) are evolved. The significant changes in dielectric parameters are due to the intramolecular and intermolecular interactions in response to the applied frequency. The permittivity spectra of stearic acid-alcohol in the frequency range of 10 MHz to 30 GHz have been measured using picoseconds Time Domain Reflectometry (TDR). The dielectric parameters (" 0 , " 0 , " 00 ) are found by bilinear calibration method. Influence of temperature in intermolecular interaction and the relaxation process are also studied. The FT-IR spectral analysis reveals that the conformation of functional groups and formation for hydrogen bonding are present in both binary and ternary mixtures of stearic acid.

The complex permittivity spectra of 2-ethoxyethanol in water solutions have been studied at different concentrations and temperatures using a picosecond time domain reflectometry technique. The complex dielectric permittivity spectrum of 2-ethoxyethanol shows Cole-Davidson type behavior. Increase in dielectric relaxation time may be due to increase in hetero molecular interaction strength. Minimum in Excess dielectric constant values provides the information about stable complex adduct. The Kirkwood correlation factor, thermodynamic properties and Bruggeman factor have also been determined and the results are interpreted in terms of hydrogen bonding and interactions among the solute -solvent molecules.

The dielectric properties of binary mixtures of benzylamine-1,2,6-hexantriol mixtures at different volume fractions of 1,2,6-hexanetriol have been measured using Time Domain Reflectometry (TDR) technique in the frequency range of 10 MHz to 30 GHz. Complex permittivity spectra were fitted using Havriliak-Negami equation. By using least square fit method the dielectric parameters such as static dielectric constant (" 0 ), dielectric constant at high frequency (" 1 ), relaxation time (ps) and relaxation distribution parameter () were extracted from complex permittivity spectra at 25 C. The intramolecular interaction of different molecules has been discussed using the Kirkwood correlation factor, Bruggeman factor. The Kirkwood correlation factor (g f ) and effective Kirkwood correlation factor (g eff ) indicate the dipole ordering of the binary mixtures.
