At the end of this section, we would like to emphasize that it is not suggested to use sobEDAw in studying interactions containing great covalent character, because the dispersion term in sobEDAw may be severely overestimated due to excessive mixing of DFT correlation term. Let us consider an extreme case, H2 molecule at equilibrium distance. Because its DFT-D3(BJ) dispersion correction term is nearly zero and thus ∆Edc/∆Eels ratio is also very close to zero, which in turn makes w close to 1, the dispersion contribution to interaction energy is almost equivalent to the contribution from DFT correlation according to the sobEDAw definition. is obviously contrary to the general understanding of the dispersion effect. We found ∆Edisp of sobEDAw at B3LYP-D3(BJ)/6-311+G(2d,p) w.CB in this case is as large as -16.9 kcal/mol, which strikingly exaggerates the role of dispersion effect in stabilizing the H2.
