Abstract

The kinetics and mechanism for the isomerization/decomposition of ClOO and OClO and the bimolecular Cl+O ₂ and O+ClO reactions were investigated at the G2M/PW91PW91/6-311+G(3df) level of theory in conjunction with statistical rate constant calculations. Results show that over 1 atm, formation of OClO has some contribution to the total rate of O+ClO reaction at low temperatures. The predicted total rate constants for the reaction appear to have a negative temperature dependence, agreeing well with experimental results.
