Abstract

The rate coefficients for the removal of O(^1^D) by reaction with the following seven bromocarbons were measured using time‐resolved vacuum UV atomic resonance fluorescence detection of O(^3^P): CH~3~Br, CH~2~Br~2~, CHBr~3~, CF~3~Br (Halon‐1301), CF~2~Br~2~ (Halon‐1202), CF~2~ClBr (Halon‐1211), and CF~2~BrCF~2~Br (Halon‐2402). The branching ratios for the quenching of O(^1^D) to O(^3^P) by the above molecules were also determined. From these measurements, the rate coefficients for reactive and nonreactive loss of O(^1^D) were calculated. These results are discussed in terms of their atmospheric relevance and trends in reactivity of O(^1^D) with hydrocarbons upon halogen substitution. © 1993 John Wiley & Sons, Inc.
