title: New electric field methods in chemical relaxation spectrometry.
abstract: New stationary relaxation methods for the investigation of ionic and dipolar equilibria are presented. The methods are based on the measurement of non-linearities in conductance and permittivity under high electric field conditions. The chemical contributions to the nonlinear effects are discussed in their static as well as their dynamic behavior. A sampling of experimental results shows the potential and range of possible applications of the new techniques. It is shown that these methods will become useful in the study of nonlinear responses to perturbation, in view of the general applicability of the experimental principles involved.
