The ab initio energies are corrected for basis set superposition error and extrapolated to the complete basis limit. Molecular van der Waals dispersion coefficients and three-body dispersion damping terms for the atom–diatomic dissociation limit are presented from a linear least squares fit and shown to be an essentially exact representation of the ab initio surface at long range.
