According to the excitation energies, the FEM performs reasonably well on this system, yielding RMSDs of the excitation energies below 200 meV for both triplet and singlet states. However, the oscillator strengths of the states S 6 -S 8 do not agree qualitatively with the reference-S 6 and S 7 should carry large oscillator strengths, but the FEM calculation yields zero oscillator strengths. Conversely, S 8 should be forbidden, but in the FEM acquires a small oscillator strength. These observations indicate that the FEM produces qualitatively wrong wave functions for those states.
