5 Å, open-shell radicals) in Figure , but not in between. While MACE is not expected to reproduce the kink at around 2-3 Å because that region of PES is not present in its training set, MACE interpolates smoothly between the singlet and the triplet states. It is desirable for the MLIP models to behave smoothly and regularly in the regions removed from the structures in its training set. While ANI-2x gives a reasonable prediction for the radical energy, the dissociation path has a large and unreasonable barrier. Although the molecule is kept rigid during this bond scan, this smooth transition in MACE is encouraging for future extensions to predictions of non-equilibrium, reactive structures.
