Welz et al. calculated an extensive potential energy surface for the γ-network, but did not calculate the corresponding kinetic rates. The present work includes all but one of the reactions examined by Welz et al. for the γ-network and added also includes decomposition pathways for three isomers: γQOOH[O], γQOOHγ, and γQOOHβ. The reaction not included in this present work, which involved a direct path from γRO 2 to γaldol + OH, was instead replaced by a reaction from γQOOH[O] to form the same products: γaldol and Table shows the barrier height differences between this work and that of Welz et al. Decent agreement, within 8 kJ/mol, occurs for all but three reactions. We report barrier heights for γAlkoxyIsom to be 20 kJ/mol lower and that of γAldolFromα to be 20 kJ/mol higher than those in Welz et al. The barrier for γC4EtherFromα was calculated to be 12 kJ/mol higher than that in Welz et al. A smaller difference of 6 kJ/mol occurs for γH2OForm, the dominant pathway at most conditions. These differences may be due to different level of theory used in the two studies, possibly amplified by multireference effects. Using the barriers given by Welz for the γH2OForm reactions does not lead to significant shifts in predicted product distribution (see Figure in the ESI † ).
