20. A reviewer has noted the difference in bandwidths for the emission and action spectra. This may be an indication that photoaquation is restricted to upper vibronic levels of the triplet states. Several examples involving the singlet state have been reported in the literature (see, for example: Vlcek, A., Jr. Coord. Chem. Rev. 2002, 230, 225-242 (especially Figures 8 and 9)).
