Volatile organic compounds (VOCs) are oxidized by ozone (O3), hydroxyl radicals, and NO3 radicals in the atmosphere. α-Pinene, one of the main biogenic monoterpenes, can be converted to highly oxidized multifunctional organic compounds, which are significantly involved in SOA formation. It is important for atmospheric chemistry to identify and quantify the oxidation products of α-pinene. In this study, we investigated the structure of the oxidation products of α-pinene and its homologues by using an atmospheric pressure corona discharge ionization mass spectrometry (APCDI-MS) and collision-induced dissociation (CID) method. We will report the relationship between the functional groups including in the oxidation products and their specific fragmentation pathways.
