behave generally similar to what was found for the Frank-Condon geometry. The FEM describes the low-lying states reasonably well, but completely misses the high-lying ones. The ECIS+FDA method produces RMSDs in the energies of 0.7-0.8 eV, leading to qualitatively wrong spectra, just like at the Frank-Condon geometry. ECISD+FDA brings the errors down to about 0.3-0.5 eV, although it is apparent that the FDA is not appropriate for MgG . ESP embedding further improves the results, with RMSDs of 0.19-0.33 eV for ECIS+ESP and 0.18-0.27 eV for ECISD+ESP, but still with some inaccuracies in the state ordering. These deviations are to a large extent due to the residual GS-LE couplings, as discussed above. Finally, EHF embedding gives satisfactory correct spectra, having RMSD values 0.1-0.2 eV and having all peaks appearing in correct energy order.
