Nonlinear dielectric relaxation of polar liquids

Molecular dynamics of two water models, SPC/E and TIP3P, at a number temperatures are used to test the Kivelson-Madden equation connecting single-particle collective dielectric relaxation times through Kirkwood factor. The relation is confirmed by simulations estimate nonlinear effect electric field on time. We show that main comes slowing down rotational relative contribution field-induced alteration factor insignificant for water. Theories need mostly account rotations single dipole in polar liquid.
