✦ Synopsis

The non-linear dielectric effect (NLDE). that is the increase in the dielectric constant divided by the square of the applied field, is measured for a number of non-polar molecular liquids and for iiquid xenon. The values of the NLDE are compared airh resufts in the literature and with values predicted by theory. The agreement with other e~per~ents is quite _eood, but with theory is very poor. the only exception being Liquid Xenon. where agreement isgood. A possible explanation is given. The prediction that the NLDE should increase strongly near the critical point due to the divergence of the isothermal compressibility could not be established by csperiment. The conclusion is drawn that this failure is due IO the reduction by the theory of second-order effects to fist-order thermodynamic and molecular properties.
