We have carried out completely numerical molecular-orbital calculations (i. e. , no linear-combination-of-atomic-orbitals basis sets or cellular approximations) on 13 first- and second-row dimers from H₂ to Cl₂ in the local-density approximation. The resulting ground-state bond lengths, dissociation energies, and vibrational frequencies are reported and compared with experimental values.
Axel D. Becke (1986) studied this question.
