In summary, polarization effects are observed to be important for water where the nonpolarizable TIP3P embedding potential is shown to have shortcomings in reproducing large QM/MM calculations. However, when addressing the same question looking at all three different solvents, using a polarizable model yields results which are more comparable to the reference calculation, especially in the low-energy region. For higher lying states there appears, however, still to be discrepancies which are most likely due to coupling between the electronic states of the solute and the solvent and will be investigated in the following sections.
