Figure 5
Rate constants for (a, b) myoglobin thin films doped with increasing concentrations of NaBr (0–1.0 M in 0.1 M steps from left to right), (c, d) cytochrome c thin films doped with increasing concentration of NaCl and (e, f) horse heart cytochrome c crystals doped with NaBr, NaCl and Na2MoO4. k1 for each is shown in the top row, while k2 is shown at the bottom. Each point is the mean value of three observations. Cytochrome c crystal k2 data have been scaled to exclude a single outlier at 0.23 mGy−1. Owing to saturation effects and the difficulty in tracking the weak solvated electron signal in crystals, only the α-band has been tracked for cytochrome c crystal data. |
