. A linear fit of the MBD data affords a slope of ≈ 1.0 with an intercept of -0.3 kcal/mol, which we regard as good agreement with the benchmarks. ALMO-EDA2 dispersion energies are systematically larger, by about 1.2× or 2.8× when the "dispersionless" functional is HF-PBE or HF exchange, respectively. In our view, these results corroborate the notion that correlation effects must be removed from the definition in Eq. ( ), and also suggests that there is very little dispersion in the PBE density functional. Consult Ref.
