Reaction Pathway Identification for the compound's availability for a reaction, 32 is highlighted in dark blue color, while all other reaction pathways are depicted in grey. In this reaction pathway identification, ozone with ethene and tetramethylethene, respectively, were defined as sources whereas the hydroxyalkylhydroperoxides were defined arbitrarily as targets which will be further decompose in water. The selection of the same type of target for both CRNs allows for a direct comparison of the reaction mechanisms with experimental evidence (i.e., for reactions leading to compound 5 in Figure ).
