Abstract : The subject application permits observation of polarization changes on an electrode surface intimes as short as 25 nanoseconds. The required miniaturization of the electrolytic cell is achieved by the use of a solion. Short pulses limit electrochemical processes so that only those reactants already present at the metal/solution interface are available for reaction. Kinetic relations for polarization buildup and decay are derived and applied to this redox system for both anodic and cathodic polarization. Kinetic parameters are determined, and the equations based on the Vetter electron transfer step, with some modifications, are verified. (Author)
