INSITU ESR INVESTIGATIONS OF ELECTROCHEMICAL SYSTEMS

The combination of ESR-spectroscopic measurements with electrochemical techniques is described using a new ESR-electrochemical cell for stud ies of solid working electrodes and a computer-driven system for both the electrochemical and the spectroscopic technique. The variation of the cell construction for different applications as well as the use of signal accumulation after potentiostatic pulses is shown. In the case of a triazine the existence of two radical products in an electrode r eaction is proved using the rapid scan ESR-technique.
