1Nomenclature of species was chosen as follows: first 3 or 4 capital letters denote the parent VOC. The letter “p”, followed by the number 1 or 2, denotes the product number. In case there is an additional letter “N” or “H”, it denotes formation under low and high VOC/NOx ratio conditions, respectively. For the intermediate case of aromatic oxidation (5.5 VOC/NOx in ppbC/ppb; [63]), the average parameters of high-to-low VOC/NOx were used.
