INTERACTION ENERGY BETWEEN SOME NEMATOGENIC MOLECULES

Calculation of the interaction energies between nematogenic MBBA and PAA molecules were performed in the framework of the Rayleigh-Schrodinger perturbation theory, supplemented with the empirical repulsive term. The predominant role of dispersion interaction as well as negligibly small induction energy were found. The electrostatic contribution to the interaction energy was discussed. Some remarks relating to the possible mode of molecular motion were also made.
