Abstract
The refractive indices and densities have been measured as a function of temperature for trans-4-alkylcyclohexyl 4′-n-pentyloxyphenylester and trans-4-alkylcyclohexyl 4′-cyanophenylester in the liquid crystalline and liquid phases. The molecular polarizabilities have been evaluated by Vuks’ formula. The polarizabilities obtained are compared with those estimated from bond polarizability calculations for the molecules. The relative nematic stabilities of the cyclohexane derivatives are discussed in terms of the molecular parameters measured.
