It is worth noting jun-cc-pVDZ is only minimally augmented, with no diffuse functions at all on hydrogen and only diffuse s-and p-functions on second-row elements. To investigate whether the anomalies noted above might arise from an unbalanced selection of diffuse functions, we performed RI-MP2/def2-SVPD calculations on the L7 + bbr and S12L data sets, with DLPNO errors reported in For the L7 + bbr data set, DLPNO errors range up to 2.8 kcal/mol using normal PNO thresholds (with the largest error for bbr), although errors are smaller than 0.1 kcal/mol for some of the other complexes. Percent errors (Fig. ) are actually on par with, or even smaller than, those observed using cc-pVDZ. However, two of the S12L complexes (4a and 4b) exhibit DLPNO errors larger than 3 kcal/mol using normal-MP2 thresholds. More importantly, diffuse functions in def2-SVPD preclude the use of extrapolation because they cause errors to oscillate as a function of T CutPNO , just as we have seen with jun-cc-pVDZ. This behavior is not observed in the def2-SVP basis set [Fig. ], just as it is not observed with cc-pVDZ, and is inherent to the use of diffuse functions.
