However, the MAE (denoted by '+' sign in Figure ) is not improved and still exceeds 0.12 eV. Furthermore, meta-GGAs tend stronger to over-estimate the absorption energies compared to GGAs. Employing the RPA-approach does not result in significant improvements in comparison to the TDA-approach (see Table and Figure ). For instance, the calculated MAE from both approaches in combination with the GGA-functionals is nearly similar. Only for M06-L, the MAE is reduced by about 0.03 eV. Additionally, the RPA-approach tends to lower absorption energies than the TDA-approach. The computationally cheaper approaches, sTDA and sTD-DFT, show a comparable MAXE for GGAs (see Table and Figure ). However, the MAE of the GGA-functionals is strongly affected by the selected approach and basis set. For example, the ME and MAE of sTDA with the functional BLYP increases by about 0.1 eV when the larger def2-TZVP basis set is employed (see Table and Figure ). Changing from sTDA to sTD-DFT results also in large MAE values. The ME and MAE of a given approach-basis-set-combination is overall close to each other in all cases and thus, highlighting systematic deviations. Please note, that the sTDA approach includes empirical parameters optimized for functionals with a Hartree-Fock exchange contribution between 20% and 60% and not for pure DFT functionals. TPSS shows an improvement to the GGAs but is still significantly affected by the selected basis-set. The MAE of M06-L for sTDA and sTD-DFT is only slightly affected by the choice of basis set which is in contrast to the GGAs. To sum up, the MAE of GGAs and meta-GGAs exceeds 0.08 eV while the MAXE is reduced to 0.30 eV only for the M06-L functional. Finally, a systematic under-estimation of absorption energies, especially for the sTDA and sTD-DFT in combination with a large basis set, is observed suggesting a global scaling of the obtained energies to match better the experimental reference. This approach is rather semi empirical but allows to access excited state calculations of extended system sizes due to the low cost of pure Kohn-Sham density functional theory.
