These results are compared to benchmarks obtained at the level of coupled-cluster theory with single, double, and perturbative triple excitations [CCSD(T)]. The benchmark results were taken from various sources. For molecule X, ROY, and rubrene, the CCSD(T)/CBS benchmarks were taken from Refs. 26, 28, and 38, respectively. For axitinib, CCSD(T)/CBS results were computed here at the domain-localized pair natural orbital (DLPNO-)CCSD(T 1 ) level, 72 using Orca v. 5.0 The latter benchmarks combined MP2/CBS results with a DLPNO-CCSD(T 1 )/aug-cc-pVDZ correction, obtained using tight PNO settings and with TCutMKN = 10 -4 .
