Changes in Secondary Organic Aerosol Composition and Volatility Going from a Low to a High HO2/RO2 Regime in α‑Pinene Photooxidation
{{output}}
The mechanisms of secondary organic aerosol (SOA) formation are not yet fully understood. The relative abundance of hydroperoxyl radicals (HO2) and peroxy radicals (RO2) affects SOA properties, but chamber experiments often underemphasize the role of HO2. To c... ...
