Comparison of CW and rapid-scan spectra of BMPO-OOH in solution with a O2⋅− production rate of 6 μM/min, recorded 10 min after mixing reagents. The O2⋅− was produced by a hypoxanthine/xanthine oxidase mixture. (A) CW spectrum obtained with 55 G sweep width, 0.75 G modulation amplitude, single 42 s scan, 20 ms time constant, and 20 mW (B1 = 170 mG) microwave power. (B) The first integral of the spectrum in panel A. (C) Deconvolved rapid-scan spectrum obtained with 55 G scan width, 51 kHz scan frequency, 20 mW (B1 = 150 mG) microwave power, 100 k averages with one cycle averaged, and a total time of ∼4 s.
