[交流] 求助:复合溶剂的介电常数计算方法

请问哪位虫友有复合溶剂的介电常数计算方法？出处在哪？是用体积百分数还是摩尔百分数？谢谢了！

The problem of relative permittivity of mixed solvents (denoted by for simplicity)
was theoretically studied by Debye and Onsager [34]. Onsager derived the following
equation:
This equation can be written with good approximation as , indicating
that the permittivity of the mixed solvent changes linearly between A and
B, if it is plotted against the volume fraction of the constituent solvents. When
the interaction between the constituent solvents is weak, this linear relation holds
well. However, when the interaction is strong, a large deviation from linearity is
observed. Figure 2.9 shows the relationship between the relative permittivity and
the volume fraction of mixtures of water and organic solvents. Because acetonitrile,
acetone and tetrahydrofuran interact only weakly with water, near-linear relations
are observed for their mixtures with water. However, for DMSO and DMF,
which readily interact with water, large deviations from linearity are observed.
