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) ISOP binary mixtures at 298.15 K. Continuous lines are plotted to show trends. Parameters from Table 8. Density data required for g calculation obtained from Ref. [6]. ϕ = MB volume fraction. Molecule inside g factor panel show the gas phase calculated structures of ISOP (B3LYP/6-311++g** theoretical level). Atom color code as in Fig. 3. Blue arrows, calculated molecular dipole moment (μ = 1.33 D).
