Figure 7.

Correlation of the rates of photoinduced electron transfer (k_ET) and ground state recovery (k_S0) with previously recorded values for charge-transfer absorbance magnitude (a and c, respectively) and secondary kinetic isotope effect (b and d, respectively). Calculated photoinduced electron transfer rates from this work plotted against (e) numerically modeled donor-acceptor distances (R), and (f) ${\text{exp}}^{-R}$. Previously recorded values for charge-transfer absorbance magnitude, secondary kinetic isotope effect, and numerically modeled donor-acceptor distance data taken from (2). Red lines are exponential (log k_ET ∝ R ∝ 2° KIE (2,46)) or linear (k_ET ∝ CTε_max as both are electron transfer processes with rates related to R) fits to the data to aid the eye.
