Abstract
The anisotropy of the static electric permittivity and conductivity for the homologous series of nematics: 4-(trans-4′-n-alkylcyclohexyl)isothiocyanato-benzenes (n-CHBT) for n = 3–10 have been measured. It is shown that the odd-even effect in the dielectric anisotropy Ac is related to the perpendicular component of electric permittivity. The odd-even effect is found in n-CHBT for both the anisotropy in the conductivity and the activation energy for ionic movement.
