摘要：

The kinetics of oxygen species in the gaseous medium of a discharge singlet oxygen generator has been revisited. Vibrationally excited ozone O-3(upsilon) formed in O + O-2 recombination is thought to be a significant agent in the deactivation of singlet oxygen O-2(a(1 Lambda)), oxygen atom removal and ozone formation. It is shown that the process O-3(upsilon >= 2) + O-2(a(1)Delta) -> 2O(2) + O is the main O-2(a(1)Delta) deactivation channel in the post-discharge zone. If no measures are taken to decrease the oxygen atom concentration, the contribution of this process to the overall O-2(a(1 Delta)) removal is significant, even in the discharge zone. A simplified model for the kinetics of vibrationally excited ozone is proposed. Calculations based on this model yield results that are in good agreement with the experimental data.
