The present paper considers a biaxial nematogenic lattice model, involving particles of D 2h symmetry, whose centres of mass are associated with a three-dimensional simple-cubic lattice; the pair potential is isotropic in orientation space, restricted to nearest neighbours, and has the simpliΓΏed for
By now, nematogenic lattice models have been extensively studied in the literature dealing with liquid crystals; they usually involve cylindrically symmetric (uniaxial) particles and pairwise additive interaction potentials. On the other hand, quantum mechanical perturbation theory shows that intera
