✦ Synopsis

This article presents applications of the non-linear dielectric effect (NDE) to studies of intra-and intermolecular equilibria in liquids. It briefly describes the physical background of the two main phenomena which determine the quantity of the observed effect. These are the orientational Langevin effect and the chemical effect. The latter consists of shifting the molecular equilibria by electric field toward the more polar forms. The experimental principles of the NDE measurements under equilibrium conditions and in the dispersion region, as well as the limitations of the method, have been discussed. Applications of the NDE to studies ofchanges in free energy, enthalpy and entropy ofmolecular equilibria and to studies of kinetics of the fast chemical reactions have been discussed and illustrated.

Dielectric relaxation and the non-linear dielectric effect have been measured in dilute solutions of monobenzoylferrocene and 1,l '-acetylbenzoylferrocene, and only the non-linear dielectric effect in monoacetylferrocene. The dielectric relaxation was measured in the temperature and frequency ranges
