It is generally believed that the formation of oxidation products with considerably lower vapour pressures than the precursor compounds plays an important role in gas-to-particle conversion of terpenes by photochemical oxidation. Until recently, mainly carbonyl compounds have been identified in SOA from gas phase oxidation of terpenes, but carbonyl
