The frequency dependence of the nonlinear dielectric increment was studied for benzene solutions of the nematogenic molecule 4-(trans-4'-n-hexylcyclohexyl)isothiocyanatobenzene (C6H13CyHx-Ph-N = C = S, 6CHBT) at 25°C. The increment was induced by a quasi-static electric field of high strength (107 V/m), and its relaxation was detected by an alternating field of low strength (102 V/m) in the fre-quency range 1 MHz-3 GHz. The results are discussed in the framework of Coffey's theory.
