Although this work refers to bR 2-photon spectra, a parallel reasoning holds for Rh too, due to the similarity of the two spectra: Rh and bR give very similar outcomes in two-photon experiments; namely a very low energy S2 signature (very close to S1) has been assigned both in Rh and bR in the 2-photon experiments, which has been questioned by Andersen and coworkers. In conclusion, the assignment of the S2 feature in Rh is still far from being unbiased and fully solved.

    • both reverse (Figure 3) and direct (Table 2) analyses do roughly agree for the E113 effect, the difference in the two results being due to the different polarization that the QM environment experiences in the two approaches: In the first we do have the full electrostatic environment of the protein but not the residue under investigation, while in the second we have only the electrostatic effects of the investigated residues
