Electron paramagnetic resonance (EPR) spectroscopy has also been coupled with electrochemical measurements where radical species are involved in the electrochemical reactions. Figure 2.18 shows a cell for simultaneous electrochanical-EPR studies. The EPR measurements can be ex situ where the radicals are formed outside of the spectrometer (Figure 2.19). In addition, in combination with the flow cell design described above, one can also use electrochanical-EPR technique to monitor the generation of free radicals in a continuous stream of solutions (Figure 2.20).
