The fixed O2 concentration was ∼4 × 1016 molecule cm–3. kic is the intercept of the linear least-squares fit to the kinetic data (ksCI) measured as a function of [c-(CH2)5COO], with 2σ statistical fitting uncertainties. kuni are derived as kuni = kic – kloss, where kloss is 0.39 × kloss(CH2OO) at a given temperature and total density (see more details in the Supporting Information).
