The formation of a suite of isoprene-derived hydroxy nitrate (IHN) isomers during the OH-initiated oxidation of isoprene affects both the concentration and distribution of nitrogen oxide free radicals (NO ). Experiments performed in an atmospheric simulation chamber suggest that the lifetime of the...
