✦ Synopsis

The Sharma constant So, the isochoric temperature coefficient of volume expansivity, the isochoric temperature coefficient of internal pressure, the reduced compressibility, the reduced volume and a few other acoustic parameters are evaluated for N-(P-Hexyloxybenzy1idene)-P-Toluidine (HBT) using only the coefficient of volume expansion. The Sharma constant which was shown by Sharma to be a constant in a number of non-mesomorphic systems is bound to be a constant in the liquid crystal HBT also, investigated by the authors with the same character constant value both in the isotropic and nematic phases with anomalous behaviour and pretransitional effects at and in the immediate vicinity of the isotropic-nematic phase transition temperature. The various other acoustic parameters estimated for liquid crystal HBT investigated in the present studies are compared and discussed with the values reported by SHARMA, and by SHARMA and REDDY for certain other non-mesomorphic systems.
