The ranges of errors for D3(BJ)-corrected global double hybrids span from 0.78 to 2.40 kcal/mol in D e and from 0.03 to 0.06 Å in r e . Of all the tested functionals, unscaled global double hybrids with dispersion correction give the smallest MADs in D e , and improved r e MADs compared to their uncorrected counterparts, despite their overestimation of both binding parameters (mirroring our previous study on excimer binding ). Also, PBE-QIDH-D3(BJ) is much closer to the MADs of dispersion-corrected BLYP-based global double hybrids, and it is no longer an apparent outlier as it was when left uncorrected. Dispersion-corrected versions of the spin-scaled global double hybrids are closer to unscaled values, approaching the best of the functionals tested for D e . Additionally, the spin-scaled global double hybrids provide better MADs in r e than their unscaled counterparts, meaning their results are overall more consistent and robust.
