The temperature variations of refractive index, density and order parameter of the compounds 2-4(4'-cyanophenyl)-5-n-heptyl-1,3-dioxane (PDX) and 4-n'-pentylcyclohexyl-(4-n-pentylcyclohexane)-1-carboxylate (OS) are reported in the smectic and isotropic phases. The principal molecular polarizabilities (alpha(e), alpha(o)) and the order parameters S have been evaluated using the anisotropic internal field model (Neugebauer's approach). The theoretical estimates of the mean and principal molecular polarizabilities using the modified Lippincott-delta-function potential model are in close agreement with the values evaluated from the experimental results.
