    • In one case (2a), the two exciplex emissions are comparably weak. The rather complicated kinetic reasons for this exceptional behavior will be discussed in a future paper.

    • 2a The highly irreversible oxidation of D makes this comparison inconclusive. The near equality of these oxidation potentials has been established, however, from cases (2a and 1b) where the exciplexes equilibrate with uncomplexed A*, with equilibrium constants for the two donors differing only by a factor ∼2, which corresponds to a difference of less than 20 mV. In general, equilibration experiments are much more sensitive to differences in redox potentials than other techniques. Details of these experiments will be presented in a separate publication.

    • 2. An additional factor of ∼0.7, arising from the greater width of the reduced spectrum for the D exciplexes, is required because the normalized spectra should have equal integrals, eqs 2 and 6, rather than equal maximum values.
