|Abstract:||Anisotropy in the pair potential primarily governs the mesomorphic behaviour of the liquid crystalline molecules. The intermolecular interactions between a pair of HBT molecules have been evaluated using modified second order perturbation treatment along with multicentred-multipole expansion technique. An all valence electron method, CNDO/2, has been employed to compute the net atomic charge and corresponding dipole moments located at each atomic centre of the liquid crystal molecule. Using the results of stacking and in-plane interaction energy studies, probability calculations at varied angular and positional configurations in a molecular pair of HBT, have been carried out using Maxwell-Boltzmann formula. An attempt has been made to elucidate the nematogenic behaviour of p-n-hexyloxybenzylidene-p-toluidine (HBT) molecules.|
