“…For example, the simulation for run 1 predicts the maximum ozone formation rate at 120 min, whereas the experimental run gives the maximum rate at 80 min after the irradiation began. Although this deviation could be due to the presence of unknown radical sources as discussed by Carter et al (12,13), this problem was not pursued further in the present study since the following discussion on the relationship between (d[03]/dí)max and [OH]mai will not be affected by the delay of photooxidation.…”
