ABSTRACT

The measurement of complex permittivity spectra of binary mixtures of sugar alcohols with DMSO were carried out using picosecond time domain technique at the temperatures ranging from 283.15 K to 298.15 K. In order to obtain the dielectric parameters, the measured complex permittivity spectra were fitted to the Cole-Davidson model. These dielectric parameters are further used to evaluate the Kirkwood correlation factor and thermodynamic parameters to discuss hydrogen bond formation.
