Abstract
The dielectric permittivity of 1-methylimidazole mixtures with a wide mixture range has been studied in the frequency range of 20 MHz to 20 GHz at 298 K using dielectric relaxation spectroscopy. The complex dielectric permittivity of mixtures is well described by the Cole-Cole model. H-bonds strong effect for molecular interactions and the type of dipolar ordering that depends on the extent of substitution are estimated by the excess dielectric model, Bruggeman mixture formula model, Basey-Fisher model, and the Luzar model. A synthesis of four models reveals different aspects of the interaction of molecules, which can give us a deeper understanding of the relaxation processes.
