Some Reactions of OH(<i>v</i> = 1)

Abstract

Abstract Reactions of OH( v = 1) with HBr, O, and CO have been studied at 295°K using a fast discharge flow apparatus: equation image The reaction O + HBr → OH( v = 1) + Br was used as a source of OH( v = 1), and subsequent chemical reactions of the excited radical were followed using EPR spectroscopy. Rate constants for reactions (2b), (3b), and (6b) were measured as (4.5 ± 1.3) × 10 −11 , (10.5 ± 5.3) × 10 −11 , and &lt;5 × 10 −12 cm 3 /molec·sec, respectively. The rate constant for physical deactivation of OH( v = 1) by CO was determined as &lt;4 × 10 −13 cm 3 /molec·sec.
