Short summary
Understanding the chemistry of biomass burning plumes is of global interest. Within this work we investigated the OH radical reaction of 3-penten-2-one, which has been identified in biomass burning emissions. We observed the primary formation of peroxyacetyl nitrate (PAN), a key NOx reservoir species. Besides, PAN precursors were also identified as main oxidation products. 3-Penten-2-one is shown to be an example explaining rapid PAN formation within young biomass burning plumes.
