From: Microwave dielectric spectroscopy of pure and mixed aromatic ester solvents
Dielectric strength, Δε, and relaxation time, τ, obtained from the fit of experimental dielectric spectra according to two Debye processes and Kirkwood correlation factor, g, for x MB + (1 - x) clHEX binary mixtures at 298.15 K. Continuous lines are plotted to show trends. Parameters from Table 5. Density data required for g calculation obtained from Ref. [6]. ϕ = MB volume fraction. Molecules inside g factor panel show the gas phase calculated structures of clHEX and MB (B3LYP/6-311++g** theoretical level) for the anti-parallel arrangement of both dipoles. Atom color code as in Fig. 3 with (green) chlorine. Blue arrows, calculated molecular dipole moments.
