Paper Abstract

The paper presents the results of measurements of the static and dynamic electric permittivities (epsilon) (parallel)*(T,(omega) ) and (epsilon) (perpendicular)*(T,(omega) ) of 4-(trans-4'-n-hexylcyclohexyl)isothiocyanato- benzene(C6H13-CyHx-Bz-NequalsCequalsS, 6-CHBT). On the basis of the temperature dependence of the static permittivities, using the Maier-Meier equations, the angle (beta) between the dipole moment vector and the long axis of 6-CHBT molecule, the square of the molecular apparent dipole moment (mu) 2app and the nematic order parameter S(T), were determined. The dielectric relaxation spectra were interpreted in the frame of the molecular model proposed recently.
