Abstracts
Nonlinear dielectric spectroscopy is used to study the dynamics of the smectogenic compound 4-trans-4'-n-dodecylcyanobiphenyl in the isotropic phase as a function of its concentration in benzene. The results obtained reveal that the large, positive amplitude of the field-induced dielectric increment (Δε≈10^{-3}) and its frequency dependence observed in the nonlinear dielectric effect spectra, even far from the possible isotropic-smectic A type phase transition, are due to short range fluctuations of the electric moment. The nature of molecular formations as a result of the strong intermolecular orientational correlations is discussed.
