Energy profiles for the absorption of [8]CPP on the graphite surface have been calculated using the HF-3c (HF/minix-gCP-D3) method, which has been demonstrated to be close to the accuracy of DFT-D3 (dispersion-corrected Density Functional Theory) with large basis sets or to MP2 (Møller-Plesset perturbation theory at secondorder) calculations at the complete basis set limit, for the sublimation enthalpies of organic crystals. The HF-3c method combines a Hartree-Fock calculation employing a minimal basis set, with different corrections to explicitly account for the missing dispersion interactions, basis sets incompleteness effects, and the tendency to calculate too short covalent bonds between chemical species. The ORCA 3.0.3 package was used for this purpose.
