Molecular Orientational Ordering of a Long-Chain Mesogenic Compound
In this communication we present the order parameter values of the chain part of the compound 5- (trans -4- heptylcyclohexyl) -2- (4- cyanophenyl) pyrimidine (HCCPP) in the nematic phase, from the subtle features in the X-ray diffraction pattern and its refractive index anisotropy data.
