Abstract

Abstract Chiral 4-(2′-methylbutyl)-phenyl-4′-octylbiphenyl-4-carboxylate (CE8) has been studied by dielectric, densytometric, refractometric and X-ray measurements. Transverse and longitudinal molecular polarizabilities have been calculated from the ordinary and extraordinary refractive indices and the density of CE8 using Neugebauer', Vuks, Lorentz-Lorenz equations with both Haller and Subramhanyama extrapolation. Effective value of the molecular dipole moment and the angle between the vector of the molecular dipole moment and the long axis of molecule have been calculated from the values of parallel and perpendicular components of the dielectric permittivity in the Iso and N* phases of this compound using the Maier and Meier equation.
