Abstract
X-ray studies of two liquid crystalline compounds, viz., p-ethoxybenzylidene p-heptylaniline (2O.7) and p-butoxybenzylidene p-heptylaniline (4O.7) are reported in this paper. The compound 2O.7 shows only a nematic phase while 4O.7 exhibits SmB, SmC, SmA, and nematic phases. Using powder X-ray diffraction patterns recorded at different temperatures, the microstructural parameters, and pair correlation function of these compounds have been estimated. The results obtained are inferred in terms of molecular ordering present in their nematic and smectic phases.
