- W1621984414 abstract "Diffusive encounters of H and D atoms with O2 in water are investigated with the time‐domain EPR free induction decay attenuation technique. Given the paramagnetic triplet ground state of the O2 molecule, it is expected that all H–O2 encounters will contribute to spin dephasing, regardless of whether reaction to form HO2 occurs. In H2O the second‐order spin‐spin dephasing rate of H in the presence of O2 is 2.0×1010 M−1 sec−1 at 25 °C, with an activation energy of 14.1±0.6 kJ/mole between 8 and 80 °C. In a mixture of 90% D2O and 10% H2O, H atom dephasing is somewhat slower in the same temperature range, with a smaller activation energy. Dephasing of D atoms in 90% D2O is ca. 5%–10% slower than H, indicating that diffusion of D is slower than H. The results are analyzed in terms of other available data concerning H and O2 diffusion and the reaction rate in water. It seems clear that neither the Stokes Einstein hydrodynamic theory nor classical activated rate theory applies to the diffusion of light hydrophobic gases in water. We tentatively conclude that H–O2 spin exchange is slightly less efficient than can be predicted in the theoretical diffusion limit." @default.
