I saw in Parker et al. that an improvement to the performance of SAPT0 could be had by a scaling function that was fit to the results of the benchmark. I’ve noticed that this energy is also printed out for the total interaction energy when using F-SAPT, but not for the total interaction energies of functional groups in the F-SAPT post-processing analysis.
Is it possible to obtain this empirical correction functional group by functional group? Is it not done in post because, though possible, this is somehow the wrong methodological choice, or unreliable?
Thanks in advance for straightening me out.
