A limitation of the previous study was that it only incorporated double hybrids with A total of eight unscaled double hybrids are considered here: B2PLYP, B2GP-PLYP,[124] PBE-QIDH[125] (global double hybrids), ωB2PLYP, ωB2GP-PLYP, RSX-QIDH, ωB88PP86 and ωPBEPP86 (range-separated double hybrids). Each of these functionals has both an SOS and SCS variant except for (ω)B2PLYP where the spin scaling optimisation landed on the same parameters and thus only one, SOS variant labeled SOS-(ω)B2PLYP. Unlike our previous study the chosen unscaled functionals now include "non-empirical" double hybrids, namely PBE-QIDH and RSX-QIDH.
