The relative energies of the conformers are visualized in Fig. . Here, it is obvious that neither the eb-MFCC nor the db-MFCC scheme can reproduce the energy pattern correctly. The eb-MFCC-MBE(2) scheme shows a better trend, but still gets many relative energies wrong. The db-MFCC-MBE(2) scheme is able to rectify these shortcomings and closely follows the trend of the single-point reference calculations. Nevertheless, there are still some outliers, in particular for conformers 09 and 10 that also showed the largest absolute errors. Here, it is interesting to note that while for the other schemes there is significant error cancellation when considering the relative energies (i.e., all errors in the total energies have the same sign), this is not the case for the db-MFCC-MBE(2) results, where positive and negative errors in the total energies amplify when comparing relative energies.
