A reinvestigation of the rate constants for the reactions of ozone with cyclopentene and cyclohexene under atmospheric conditions

The rates of decay of ozone in a large excess of the cycloalkene have been re-measured by an improved experimental procedure, and the following second-order rate constants (cm³ molecule^?1 s^?1) have been determined in synthetic air at atmospheric pressure: The results are discussed in relation to existing literature data on the kinetics of ozonecycloalkene reactions.
