a The concentration profile of CO was measured after 248-nm laser photolysis of the flowing mixture of CH2I2/HCHO/O2/N2 (0.016/0.123/14.9/0.04 Torr, PT = 15.1 Torr, 296 K). b The concentration profile of CO was measured after 248-nm laser photolysis of the flowing mixture of CH2I2/SO2/O2/N2 (0.016/0.014/14.9/0.04 Torr, PT = 15.0 Torr, 296 K). c The concentration profile of CO was measured after 248-nm laser photolysis of the flowing mixture of CH2I2/O2/N2 (0.016/14.9/0.04 Torr, PT = 15.0 Torr, 296 K). d The concentration profile of CO was measured after 248-nm laser photolysis of the flowing mixture of HCHO/O2/N2 (0.123/14.9/0.04 Torr, PT = 15.0 Torr, 296 K). e The corrected concentration profile of CO represents the net production of CO by the reaction CH2OO + HCHO. f The concentration profile simulated using the kinetic model shown in Supplementary Table 3. Here, the data correspond to the experiment 1 listed in Supplementary Table 4.
