Rate constants for the gas‐phase reactions of O 3 with the carbonyls acrolein, crotonaldehyde, methacrolein, methylvinylketone, 3‐penten‐2‐one, 2‐cyclohexen‐1‐one, acetaldehyde, and methylglyoxal have been determined at 296 ± 2 K. The rate constants ranged from <6 × 10 −21 cm 3 molecule −1 s −1 for acetaldehyde to 2.13 × 10 −17 cm 3 molecule −1 s −1 for 3‐penten‐2‐one. The substituent effects of CHO and CH 3 CO groups on the rate constants are assessed and discussed, as are implications for the atmospheric chemistry of the natural hydrocarbon isoprene.
