Long-range components of coefficients of SO(3)-invariant expansions of intermolecular forces (8-coefficients) have been studied for Lennard-Jones interactions between force centers (atoms). In a simple geometrical model, a new effect has been discovered, consisting in inversion of the 8-coefficient dependences upon intermolecular distances as function of molecular anisometry. Possible manifestations of this effect in experimentally observed properties of complex liquid and liquid crystalline systems are discussed, as well as its role in formation of microheterostructures.
