Unscaled global double hybrids were used as implemented in ORCA 5.0.3. While our previous study also presented (ω)B2(GP-)PLYP results for these same four systems, we recalculate them here with the RI-approximation, consistent with the default implementation of double hybrids in ORCA 5.0.3, which was not the case for the group ORCA version originally used in the previous paper.
