SINGLET ORIENTATIONAL DISTRIBUTION FUNCTION AND DIELECTRIC PERMITTIVITY OF DIPOLAR SPHEROCYLINDERS IN THE NEMATIC PHASE

Monte Carlo simulations are used to investigate the orientational properties of the nematic phase of a liquid crystal model consistent of spherocylinders with a strong longitudinal central dipole moment. The results are contrasted with those for the non-polar case and for real strongly polar liquid crystals. The singlet orientational distribution function is analysed in the light of approximations commonly made to analyse scattering experiments. The validity of various theoretical approximations for the dielectric constant is discussed.
