- The nonlinear spectra of 4,4'-n-hexylcyanobiphenyl (C$\text{}_{6}$H$\text{}_{13}$-Ph-Ph-CN) in benzene solutions were recorded in the frequency range of 300~kHz-100~MHz in the presence of the strong static electric field E$\text{}_{0}$=1.1×10$\text{}^{7}$ V/m, at 25˚C. The dynamic pretransitional phenomena revealed for polar C$\text{}_{6}$H$\text{}_{13}$-Ph-Ph-CN were interpreted in the frame of the Landau-de Gennes theory. The identical concentration-dependent behavior of nonlinear relaxation time in the vicinity of the transition from the isotropic to the nematic phase for polar and nonpolar compounds was discussed.
