an unbalanced approximation unless all three energies are computed in the same (dimer) basis set. Despite its easy-to-understand provenance, use of the CP procedure has been controversial, and remains so in some more recent work. The chronological evolution of this controversy is detailed in Section 1 .2 but the gist is a perception that the CP procedure "overcorrects" ∆E int . When small, monomer-centered basis sets are used, |∆E int | is much too large as compared to the complete basis set (CBS) limit computed at the same level of theory, but |∆E int | may be too small upon CP correction. This observation is not an indictment of the CP procedure per se, because BSSE is interwoven with basis-set incompleteness error (BSIE). Due to partial compensation of these effects, it has been suggested that fixing one of these issues (namely the BSSE, by means of the CP procedure) without fixing the other (BSIE, by use of larger basis sets) results in an approximation that is also unbalanced. The use of a "half-CP" procedure, which averages the CP-corrected and uncorrected values of ∆E int , can be seen as a remedy for imbalance. For correlated wave function methods, the half-CP average converges to the CBS limit faster than either the corrected or uncorrected interaction energy on its own. For DFT, there is an additional consideration in that the performance for noncovalent interactions varies greatly from one functional to another, and finite-basis error may offset inherent functional error in some cases. To the extent possible, one should therefore attempt to uncouple these errors by examining the performance of DFT in the CBS limit. Although the CP procedure has been carefully benchmarked for correlated wave function models, its behavior in DFT calculations has not been examined so systematically. A recent comparison with explicitly-correlated wave function results recommended CP correction for converging DFT to the CBS limit, although the selection of basis sets and functionals was somewhat limited. Another assessment of dispersion-corrected GGA functionals using Dunning basis sets concluded that CP-corrected aug-cc-pVDZ results were close to quadruple-ζ results but that uncorrected aug-cc-pVDZ results were not. The systematic examination contained herein considers a wider variety of functionals and basis sets that are more typically used for DFT calculations.
