The reactions of atomic oxygen and halons

Abstract

The mechanisms of the reactions of atomic oxygen and halons were studied in this paper. The final products of the reaction of O (¹D) and CF₂ClBr were CF₂O, Cl₂ and Br₂, with the rate coefficient of 0.90xl0⁻¹⁰ cm³ molecule⁻¹ s⁻¹. While the reaction of O (^lD) and CF₃Br yielded CF₂O, F₂ and Br₂, with the rate coefficient of 0.98×10⁻¹⁰ cm³ molecule⁻¹ s⁻¹. The role of buffer gases in these reactions also has been discussed. This study on the reactions of atomic oxygen and halons is helpful in understanding the stratospheric ozone depletion process.

Key words:

• Atomic oxygen
• Halons
• UV‐light
