Short summary

A series of OH-initiated oxidation experiments of trimethylbenzene were investigated in the absence and presence of NO_x. Many C₉ products with 1–11 oxygen atoms and C₁₈ products presumably formed from dimerization of C₉ peroxy radicals were observed, hinting at the extensive existence of autoxidation and accretion reaction pathways. The presence of NO_x would suppress the formation of highly oxygenated C₁₈ molecules and enhance the formation of organonitrates and even dinitrate compounds.
