Abstract

Specific-volume measurements on methoxybenzylidene butylaniline (MBBA) and $p$-azoxyanisole (PAA) using the differential-dilatometer method are reported. The nematic-isotropic pretransition region over a range \ifmmode\pm\else\textpm\fi{} 15\ifmmode^\circ\else\textdegree\fi{}K about the transition point is examined. The data, interpreted in terms of the de Gennes-Landau theory, are consistent with an $\ensuremath{\alpha}=0.5$ critical exponent. The pseudocritical temperature derived from the volume data is significantly different from that reported for optical experiments.
