Abstract

The paper presents the results of measurements of the static and dynamic electric permittivities (epsilon) <SUB>(parallel</SUB>)<SUP>*</SUP>(T,(omega) ) and (epsilon) <SUB>(perpendicular</SUB>)<SUP>*</SUP>(T,(omega) ) of 4-(trans-4'-n-hexylcyclohexyl)isothiocyanato- benzene(C<SUB>6</SUB>H<SUB>13</SUB>-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) <SUP>2</SUP><SUB>app</SUB> and the nematic order parameter S(T), were determined. The dielectric relaxation spectra were interpreted in the frame of the molecular model proposed recently.
