An important aspect of this work is convergence of the DLPNO approximation with respect to various PNO thresholds, and several PNO-related settings have been tested. ORCA's documentation 94 suggests different hierarchical thresholds for MP2 versus CCSD(T), although Large supramolecular complexes investigated in this work, including the L7 complexes, 61 S12 complexes, 62,63 a buckyball-in-a-ring complex (bbr), graphene dimers from the circumcoronene family, and the corresponding graphane (perhydrocircumcoronene) dimers.
