In addition to these well-established families of basis sets, we also tested "calendar" versions of the correlationconsistent basis sets, in which diffuse functions are systematically removed starting from aug-cc-pVXZ. (These basis sets were added to Q-Chem as part of the present work.) The jul-cc-pVXZ basis sets (for X = D, T, or Q) consist of cc-pVXZ for hydrogen and aug-cc-pVXZ for other atoms, meaning that there are no diffuse functions on hydrogen. The jun-cc-pVXZ basis sets additionally remove the diffuse functions with highest angular moment from each non-hydrogen atom. We note that juncc-pVDZ has been suggested as a compromise basis set for SAPT0 calculations, exploiting the slow basis-set convergence of the dispersion energy to limit the intrinsic overestimation of dispersion by second-order perturbation theory. This is a compromise because electrostatics is not generally converged at the double-ζ level, but overall errors in SAPT0 interaction energies are worse in aug-cc-pVDZ and larger basis sets, as compared to jun-cc-pVDZ, suggesting that it is more important to control the error in second-order dispersion rather than to converge the electrostatics.
