Dielectric relaxation and thermodynamic study of polyhydric sugar alcohols in DMSO using TDR technique

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.
