We further test the accuracy of the Padé local interpolation in Fig. , which shows the dissociation curves (total energies) of H 2 and LiH computed within the spin restricted formalism. For comparison, HF energies (i.e., E c ≈ 0) are also shown, along with "λ = 1" energies, representing the sum of HF energies and the correlation energy given by E c = E λ=1 c . As anticipated from the monotonically decreasing behavior of E λ c , the "λ = 1" energies are significantly lower than the true (i.e., λaveraged) correlation energies. The plot also shows that the Padé-interpolated energies (Eq. 43) are very accurate near equilibrium and at intermediate bond lengths, but their accuracy deteriorates at larger separations (beyond 2 Å for H 2 and 3 Å for LiH).
