In DMSO, the reference one-photon absorption spectra are presented in Figure for solutes 1 (Figure ) and 2 (Figure ). Replacing the quantum mechanically treated DMSO molecules with the polarizable DMS solvent model yields the blue spectra in Figure For the neutral solute 1, the obtained results are very much like the results obtained for both water and CHCl 3 . The major peak at around 4.2 eV is reproduced with good accuracy (< 0.1 eV for the position) and in the high-energy range, the peak positions are shifted around 0.1 eV to the right. The peak heights are, however, reproduced with good accuracy. For the anionic solute 2, the major peak at 3.3 eV is reproduced with very good accuracy also in terms of peak height. Here, it is seen that only the 5+ eV range fails to reproduce the reference spectrum. The deviations from the reference spectrum computed from eq 13 is 0.27 and 0.24 for solutes 1 and 2.
