| Abstract: | The degree of ozone recovery after pulsed UV laser photolysis of O2-O3-Ar mixture is measured using time-resolved absorption spectroscopy. The effect of incomplete ozone recovery in the presence of molecular singlet oxygen O2(a 1Δ) and atomic oxygen is detected. This effect is caused by the reaction between the vibrationally excited ozone molecule formed due to recombination and atomic oxygen. The branching factor for the chemical channel of reaction products is γ r = 0.81 ± 0.13. |
