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) 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).
