The measurement of complex permittivity spectra of binary mixtures of Erythritol with DMSO were carried out using picosecond time domain technique at the temperatures ranging from 10 °C to 25 °C 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 the hydrogen bond interaction
