    • (d) Note that the ion-pair separation processes described in ref 37b do not pertain to the excited TCNE complexes, since the ion-pair collapse in eq 4 occurs with unit efficiency on the picosecond time scale. No absorption of the separated ions was observed (see the Experimental Section).

    • (a) The slight slope of the linear fit (β = 0.2) is negligible compared to the error limits (±20%) of the kinetic measurements, (b) In the case of benzene/TCNB complexes (see entry a in Chart I), the data were operationally fitted to a straight line, although some curvature in the data points was apparent (see Figure 5).
