    • 2 exhibits more complicated structure than that observed in glassy solution. One possible explanation is that there may be more than one distinct cation site in the solid (which has not been crystallographically characterized)

    • A weak shoulder also is observed near 380 nm in the excitation spectra of the protonated complexes. Since the deprotonated complexes absorb strongly in this region, the possibility of emission from the residual deprotonated complex cannot be excluded

    • 3, 77 K glassy solution emission spectra of the nominally pure deprotonated complexes generally show a weak emission component similar to that of the protonated complex. However, the major component of emission for these samples is identical with the single emission observed in the presence of base

    • 40 Emission and absorption spectra for the former retain their characteristic sharp vibronic structure, while absorption features of the latter are much broader, presumably because of the expected large distortion along low-frequency metal-ligand deformation coordinates in the MLCT excited state.57 This example has the peculiarity that the MLCT and LL excitations in question involve different ligands of the complex. Thus, mixing should be intrinsically small, and the situation is not strictly comparable to the compounds of the present study

    • Since we are considering triplet states in the presence of a heavy metal atom (Pt), spin-orbit coupling should of course be considered in a complete treatment. But in the low symmetry of these complexes, the group-theoretical result is simply that, in principle, all triplet states can mix with all other triplet states
