The DF-SAPT-DFT interaction energies of 15 hydrogen-bonded systems were confronted with their supermolecular counterparts obtained by combining the R1-MP2/CBS and CCSD(T)/aug-cc-pVDZ results. The former were assumed to approach the CBS limit by the power law, whose exponent was estimated by fitting the two sets of interaction energies in the least-squares sense.
