Table 14. Mean Absolute Errors (MAEs) in 0–0 Transition Energies (eV) Calculated with the OMx/MRCI, OMx-D3T/MRCI, and ODMx/MRCI Methods for the SKF Set Relative to Back-Corrected Experimenta.
OM2 | OM2-D3T | ODM2 | OM3 | OM3-D3T | ODM3 | |
---|---|---|---|---|---|---|
countb | 68 | 67 | 65 | 66 | 66 | 65 |
MAE | 0.26 | 0.26 | 0.25 | 0.27 | 0.27 | 0.27 |
Experimental values were back-corrected with (TD)DFT ΔZVPE values to directly compare them with theoretical calculations, which do not include ZPVE-corrections, see ref (55) for the reasons.
Some calculations could not be converged which reduces the total count of successful computations to less than 68. Tests have confirmed that this practically does not affect the overall statistics.
