(A) X-band EPR spectra of DMPO (100 mM), FeCl3, and H217O (20% 17O atom). (B) Simulation of A (DMPO•-16OH: aN = 14.96, aβ-H = 14.68; DMPO•-17OH: aN = 15.11, aβ-H = 13.93, a17-O = 4.81). (C) Spectra of DMPO (100 mM), (NH4)2S2O8, and H217O. (D) Simulation of C (DMPO•-OSO3H: aN = 13.74, aβ-H = 9.93, aγ-H1 = 1.47, aγ-H2 = 0.57; DMPO•-16OH: aN = 15.01, aβ-H = 14.74; DMPO•-17OH: aN = 15.02,, aβ-H = 13.84, a17-O = 4.84). Literature value for DMPO•-17OH: aN = 15.01, aβ-H = 15.01, a17-O = 4.66.62
