The Kinetics of Formation and Dissolution of Condensed Coumarin Films.

Abstract

Following stochastic nucleation, the resulting capacitance change is used to trigger a change in the applied potential in order to study growth and dissolution at potentials which are otherwise difficult to access. Experimental results show that the dissolution rate depends on the age of the compact film. By using simultaneous measurements of current-time and capacitance-time curves under circumstances where film formation is stochastic, the possible origin of some so far unexplained maxima on polarographic current-time curves reported in the literature has been identified. These reflect charging currents accompanying the formation of condensed films
