(a) XANES-EC measurements under the reducing potential of −0.45 V and the oxidative potential of 1.05 V for Cu:Aβ4–16 at room temperature. The low-temperature data are also given for comparison. (b) Enlarged XANES-EC spectra showing a slight peak at 8979 eV, corresponding to the 1s–3d transition, at the 1.05 V potential. CuII in the mixture slightly increases the oxidation potential. (c) XANES-EC measurements under the reducing potential of −0.05 V and the oxidative potential of 0.95 V for Cu:Aβ4–12 at room temperature. (d) Enlarged XANES-EC spectra showing a very slight peak at 8979.4 eV, corresponding to the 1s–3d transition, at the 0.95 V potential.
