Abstract / Full Text

The static permittivity of water–DMSO mixtures is measured in the interval of 293–323 K throughout the range of concentrations of water–DMSO mixtures. Static permittivity values of the mixtures reveal a deviance from additivity that is maximal in the area of  0.3–0.4 molar shares of DMSO, where complexes 1DMSO–2H2O can form through H-bonds. The calculated values of the Kirkwood correlation factor gK indicate antiparallel orientation of DMSO dipoles, especially in the range of high DMSO concentrations of  0.7–1.0 molar shares.
