Dependence of Mesogen Molecules Interaction Energy on their Mutual Orientation
For interaction energy of mesogenic model rod-like molecules an analytical expression is obtained. Interaction energy of dipole moments interaction is much less than the total interaction energy. The empirical Rapini-Papoulard potential for the free surface energy of liquid crystals corresponds well with a limiting case of the expression obtained for small orientation angles.
