(a) 77 K X-band EPR spectrum of ToMOCNO prepared by incubating 250 μM ToMOCox with 10 equiv DEANO for 1 h at 25 °C. (b) 77 K EPR spectrum of (a) treated with 1 equiv of Na2S2O4; the asterisk denotes a small amount of signal from (a). Instrument parameters: 9.332 GHz microwave frequency; 0.201 mW microwave power; 5.02 × 103 receiver gain for (a), 1.00 × 103 for (b); 100.0 kHz modulation frequency; 8.00 G modulation amplitude; 40.960 ms time constant.
