Correcting ab initio-based potential energy surfaces (PESs) has been a long-standing goal of computational chemistry. Several approaches dating from 30 years ago have been suggested. In one, a correction potential is added to an existing PES, and parameters of the correction potential are optimized by matching ro-vibrational energies to the experiment.1–3 This approach relies on being able to calculate exact rovibrational energies to make the comparison with the experiment robust. Thus,...
