abstract = "For the prototypical diatomic-molecule diatomic-molecule
interactions H-2-HX and H-2-X-2, where X = F, Cl, Br,
quantum-chemical ab initio calculations are carried out on grids
of the configuration space, which permit a spherical-harmonics
representation of the potential energy surfaces (PESs). Dimer
geometries are considered for sets of representative leading
configurations, and the PESs are analyzed in terms of isotropic
and anisotropic contributions. The leading configurations are
individuated by selecting a minimal set of mutual orientations of
molecules needed to build the spherical-harmonic expansion on
geometrical and symmetry grounds. The terms of the PESs
corresponding to repulsive and bonding dimer geometries and the
averaged isotropic term, for each pair of interacting molecules,
are compared with representations in terms of a potential function
proposed by Pirani et al. (see Chem. Phys. Lett. 2004, 394, 37-44
and references therein). Connections of the involved parameters
with molecular properties provide insight into the nature of the
interactions.",
