Experimental (black) and simulated (red) EPR spectra obtained upon irradiation (λmax = 365 nm; irradiance 15 mW∙cm−2; exposure 400 s) of the aerated TiO2 P25 suspensions in mixed solvent water/DMSO (5:1 v:v) in the presence of various spin trapping agents (TiO2 concentration 0.167 mg∙mL−1): (a) DMPO (SW = 8 mT; c0,DMPO = 0.035 M); (b) DBNBS (SW = 10 mT; c0,DBNBS = 0.008 M); (c) DBNBS using DMSO-d6. The spin Hamiltonian parameters of corresponding spin-adducts are listed in Table 2. (a) •DMPO-CH3 (relative concentration in %, 94), •DMPO-OH (6); (b) •DBNBS–CH3 (100); (c) •DBNBS-CD3 (100).
