Monoterpenes are volatile organic compounds (VOC) that are emitted into the atmosphere from biogenic sources, such as trees and vegetation, or from anthropogenic sources, such as consumer care products. The mean global emission of monoterpenes is estimated to be 160 Tg a year. In the atmosphere, the monoterpenes react with the main oxidants, the OH radical, ozone (O3), or nitrate radicals (NO3). Products of these oxidation reactions influence the atmospheric composition. Especially formation and growth of organic aerosols and the formation of ozone canhave effects on air quality, human health and climate warming. The oxidation of atmospheric organic compounds by the OH radical initiates a radical chain reaction that involves hydroperoxy radicals (HO2) and organic peroxy radicals (RO2, R=organic group). Depending on the environment, the RO2 radicals can either undergo bimolecular reactions with NO, HO2 or other RO2, or unimolecular reactions. Unimolecular reactions of RO2 include H-shift reactions and endocyclizations. From these autoxidation reactions, higher oxidized species can be formed rapidly.Whether unimolecular reactions of RO2 are competitive with bimolecular reactions is also highly dependent on the molecules structure. Detailed knowledge about the oxidation mechanism of atmospherically relevant species is crucial for understanding the atmospheres’ oxidation capability |
