2 (curve C) D = 4 X cm2/s. This corresponds, according to the Dahms-Ruff equation~~10 to the rate constant of the electron exchange of ca. 2 X lo4 M-' s-l. The latter is two orders of magnitude smaller than a value obtained for a homogeneous solution." $7. 4 The results presented here are the first measurements of the lateral electron transport directly at… (More)
