Pressure-volume isotherms of 4-(<I>trans</I>-4-pentylcyclohexyl)benzonitrile were directly measured by means of piston-cylinder method at various temperatures. From the relation of the molar volume and the transition temperature which was determined by its clearing point, the parameter ∂ln<I>T</I><SUB>c</SUB>⁄∂ln<I>V</I><SUB>c</SUB>, was found to assume a value of −5.24, which should be closely related with the intermolecular potential energy. The value of this parameter increased correlatively with the alkyl chain length in the homologous series of 4-(<I>trans</I>-4-alkylcyclohexyl)benzonitriles.
