Short summary
Terpinolene is an isomeride of limonene, with a high secondary organic aerosol (SOA) yield. The comparative analysis of OH-initiated (daytime) and NO3-driven (nocturnal) terpinolene oxidation mechanism, highlighted the formation of nitrogen-containing oxygenated organic molecules (OOMs), would be conducive to molecular structures identification of OOMs in atmospheric monitoring and atmospheric chemical model refinement.
