Abstract
Static dielectric constants of two nematogenic compounds viz., (i) 1-hexyl-4-(4-isothiocyanatophenyl) bicyclo [2 Urban , S. , Gestblom , B. , Brickert , T. , & Wurflinger , A. Z. ( 1995 ).

[Google Scholar]] octane and (ii) 4′-(pentyloxy)-4-biphenyl carbonitrile, have been measured at different temperatures using a sensitive LCR bridge. Using these data the dipole moment associated with the molecules is estimated. The validity of this approach is discussed by comparing the order parameter S obtained from the refractive index data with the values of S computed from the predications of the mean-field theories. Boardewijk's theory is applied here with appropriate molecular parameters, to compute dipole-dipole correlation factors.
