Abstract
The kinetics of ClO{sub 2} photodecomposition in trichlorofluoromethane solutions induced by 337.1-nm pulses were investigated under various experimental conditions. Instantaneous photochemical bleaching is followed by a slower bleaching which follows pseudo-first-order kinetics and leads to the formation of a long-lived transient species absorbing up to 330 nm with {lambda}{sub max} {approx} 280 nm. At high concentrations of ClO{sub 2} identical amounts of chlorine dioxide are consumed in both stages, revealing that the latter involves stoichiometric reaction of an initially formed intermediate with excess ClO{sub 2}. Addition of tetramethylethylene, a very efficient oxygen atom quencher, had no detectable effect on the kinetics of ClO{sub 2} decay. The intermediate is therefore identified as ClO and the new species as Cl{sub 2}O{sub 3}, chlorine sesquioxide, formed by reaction 5: ClO + ClO{sub 2} {yields} Cl{sub 2}O{sub 3}.
