eV. Introducing the protein and solvent broadens and redshifts the lowest band (by about 0.2 eV), irrespective of the model used to describe the environment. For this transition, the absorption bands are almost identical. For the transitions at higher excitation energies, the results are also similar, with several low-intensity bands between 4-5 eV, followed by an intense band at 5.5 eV (corresponding to a 0.2 eV redshift compared to the gas-phase result).
