摘要
The complex dielectric permittivity spectra (CPS) of a binary mixture of 1,5-pentanediol (1,5-PD) with 1,4-dioxane (1,4-DX) were determined using time-domain reflectometry in the frequency range of 10 MHz to 30 GHz. The experimental CPS data were fitted to the Cole-Davidson equation using a nonlinear least squares fit method to determine the dielectric relaxation parameters. The intermolecular interactions in the binary liquids were studied through the Kirkwood correlation factor, excess parameters, thermodynamic parameters, and Bruggeman's factor.
