Notes:
The laser photolysis-long path transient absorption technique was used to study the mechanism and products of the reaction O(3P) + OClO (→M) Products (3) at 260 K in 100 to 400 torr of He, N2, and Ar. ClO was not detected as a reaction product, 〈5% yield, from this reaction at 400 torr and 260 K. A broad UV absorption feature associated with a product of this reaction, with a peak located at 260 nm, was observed. The peak absorption cross section of this species was measured to be (1.72 ± 0.12) × 10-17 cm2 molecule-1. The rate coefficient for the appearance of this species was measured to be (1.69 ± 0.46) × 10-13 cm3 molecule-1 s-1 and was independent of pressure. The rate coefficient for the appearance of the species is ca. 10 times lower than that for the disappearance of O(3P), indicating that the observed species is not a direct product of the reaction of O(3P) with OClO. Mechanistic considerations and the possible identity of the absorber are discussed. © 1997 John Wiley & Sons, Inc.
