Short summary

OH radicals are important intermediates in the atmosphere, and the high concentrations observed in tropical regions are yet to be fully explained. Radical-radical reactions such as the title reaction can contribute to OH formation. This is the most fully comprehensive study of the CH₃C(O)O₂ + HO₂ reaction with direct observation of products in all reaction channels. The implications of the new measurements on OH, PAN and NO_x concentrations are considered via global models.
