Dielectric relaxation study of 1-pentanol-ethanol binary mixtures at 10 MHz-50GHz frequency range using TDR technique

The dielectric measurements have been executed by making the use of time domain reflectometry (TDR) technique for 1-pentanol and ethanol in the pure form and for their binary liquid mixture in the frequency interim of 10 MHz-50 GHz at varying temperatures, respectively. The complex permittivity spec...

Description
Summary:The dielectric measurements have been executed by making the use of time domain reflectometry (TDR) technique for 1-pentanol and ethanol in the pure form and for their binary liquid mixture in the frequency interim of 10 MHz-50 GHz at varying temperatures, respectively. The complex permittivity spectra studied show Debye behaviour and plotted as the function of frequency. The temperature-dependent dielectric constant and relaxation time values were estimated. The Kirkwood correlation factor (g eff ) has also been studied to determine the alignment of dipole moments in mixture. The thermodynamic parameters and temperature-dependent behaviour of relaxation time, i.e. Arrhenius plot, have been studied.
