✦ Synopsis

the formation of higher oxides of chlorine such as Cl 2 O 4 , Cl 2 O 6 , and Cl 2 O 7 has been observed [5 -8]. The reaction mechanisms are not understood but may involve the formation of ClO 3 which has recently been observed in an inert matrix [9]. In these systems, ClO 3 can be formed via the addition of O( 3 P) to 11] have shown that the rate coefficient for the reaction of O( 3 P) with OClO (3) increases at higher pressure and lower temperatures strongly suggesting the formation of an adduct. Adduct formation in Reaction (3) could also lead to errors in photochemical studies where Reactions (1) or (2) have been used as a source of ClO radicals. Indeed, many of the results obtained with this source of ClO differ from those using other ClO sources.

In this article, we present a study of the O( 3 P) ϩ OClO reaction at high pressure and low temperature.

EXPERIMENTAL
