where aRMSD min and rRMSD min denote minimal values of Equations 2 and 3, obtained with optimal s abs and s rel according to Equations 4 and 5, respectively. The resulting scaling factors and corresponding aRMDS values obtained by the procedure described in Section 2 are given in Table . There are a few trends that can be observed. First of all, s rel ≥ s abs for each given method. Secondly, the scale factors for the DF-D3(BJ)/B methods are within accuracy compared to DF-D4/B, suggesting that the effects of D3(BJ) and D4 corrections are similar. The last trend observed is a systematic decrease of the aRMSD values upon improving the basis set quality, namely aRMSD(DF-Dn/def2-TZVP)≤aRMSD(DF-Dn/def2-SVP)≤aRMSD(DF-Dn/6-31G).
