EPR spectra with 1.25 N-TiO2 in DMPO/DMSO solutions with bubbling of oxygen, air, and argon in (A) dark condition (B) under visible irradiation, and (C) simulated spectra. DMPO-OOH: g=2.0055, aN=13.9 G, aβ-H=10.1 G, aγ-H=1.4 G; DMPO-alkyl: g=2.0053, aN=15.8 G, aβ-H=22.4 G, aγ-H=0.6 G.

Notes: Literature values: (DMPO-OOH in DMSO: aN=12.7 G, aβ-H=10.3 G, aγ-H=1.3 G; DMPO-CH3 in water/DMSO: aN=16.1 G, aβ-H=23.0 G).32 Simulations correspond to % compositions of % alkyl–% OOH adducts of 7%–93% in oxygen, 17%–83% in air, and 12%–88% in argon.
