For each of the investigated interactions, the energies of the lowest-lying quadruplet and doublet radical fragments MO + SO that vary only in the spin of the unpaired parallel electrons of the SO fragment were calculated at CASSCFMRMP2 level of theory.
Among the 4-letter alphabet potentials, the one based on full structure tessellations (i.e., no edge-length cutoff) outperformed that using a 12 [Angstrom] cutoff; however, the latter case is preferable since, without a fixed cutoff, false-positive atomic quadruplet interactions are admitted into the analyses based on those tessellations.
