Election spin resonance measurements were performed at X-band frequencies using a spectrometer Model JES-3B-365,manufactured by the Japan Electron Optics Co., employing 100 kc. field modulation. The cell for electrogeneration was similar to that used by Adams, et al. Generations were performed in the microwave cavity of the ESR spectrometer using the technique of Geske and Maki. Hyperfine coupling constants were measured by careful comparison with the splitting of Mn^<2+>in magnesium oxide. The value of 86.8 gauss was taken for the Mn^<2+>splitting. Preparation and purification of polynitroparaffins were previously given. Samples were dissolved in 50% aqueous acetonitrile solution containing 0.1M potassium chloride as the supporing electrolyte to 5mM. Cathode potentials were controlled against a saturated calomel electrode. Oxygen in the cell and dissolved in the solution was removed by purified nitrogen gas. We thand Japan Electron Optics Co. for measurement of ESR spectrum.
