### Abstract

An equation is deduced for the field dependence of relative permittivity of liquids making allowance for the field dependence of the Kirkwood g factor too. The equation gives predictions on both normal and anomalous dielectric saturation as well as on the structure-breaking or structure-making effect of the field. Comparison with experimental data indicates that the field dependence of the g factor can alter significantly the nonlinear coefficient Δε/Ε^{2} calculated for some alcohols, water, and nitrobenzene. Comparison is also made with approximations, published previously. It is indirectly confirmed that the dielectric behavior of liquids can be described by the same equation even in the vicinity of ions in electrolyte solutions, provided that the average field strength, calculated on the basis of the lattice model of electrolytes, does not exceed the value of about 10 ^{4} esu. This is about 100 times stronger than the maximum field applied in macroscopic measurements of the nonlinear coefficient.
