Two-Dimensional Free Energy Surfaces for Electron Transfer Reactions in Solution

Figure 6

Observed decay curves (dots) of fluorescence of C522 quenched by TMPD (0.2 M) in liquid paraffin at 296 K, calculated best-fit to it (solid line), hypothetical decay curve (broken line), and residuals (upper dots). The thin solid line indicates the instrument response function. The ET parameters obtained are 𝑅₀=12.2 Å  and 𝑘₀=3.7×10¹⁰ s−1, respectively, with 𝜒²=1.2786. See the text for the hypothetical decay curve.
