摘要：

4-n-Decylphenyl-3 prime -methyl-4 prime -(4 double prime -nitrobenzoyloxy)benzoate (10 PMNBB) which exhibits the smectic A and nematic mesophases shows a large expansion ( approximately equals 20%) of the bilayer spacing as it is cooled in the mesomorphic range. This is accompanied by a reversal in the sign of the dielectric anisotropy which becomes negative at lower temperatures.
