Chemical Bond - Comparison of Valence Bond and Molecular Orbital Theory
... In some respects valence bond theory is superior to molecular orbital theory ... When applied to the simplest two-electron molecule, H2, valence bond theory, even at the simplest Heitler-London approach, gives a much closer approximation to the bond energy, and it provides a much more accurate ... why the curve of total energy against interatomic distance for the valence bond method lies below the curve for the molecular orbital method at all ...
