Abstract

New results are presented of nonlinear dielectric effect (NDE) measurements in the isotropic phase close to T^C for HCPB, 5CB, and 8CB. With a measurement field frequency of about 6 MHz deviations from the Landau-de Gennes model were observed. This is interpreted as due to the influence of the orientation mechanism of individual molecules which becomes a dominating influence in the range of sufficiently high frequencies.
