The photolysis of CH 3 OH/Cl 2 /air, CH 3 OH/Cl 2 /NO 2 /air, and (CH 3 ) 2 CHOH/Cl 2 /NO 2 /air at 28 ± 2°C was studied using the long‐path FTIR method. The primary reactions of methanol and isopropanol with Cl atoms were α‐hydrogen abstraction (100%), and α hydrogen (85%), and α‐hydrogen abstraction (15%), respectively. The failure to detect hydroxyalkyl‐peroxy nitrates suggested that the oxygen addition to α‐hydroxy radicals is not important. From the product distribution an upper limit of the ratio of oxygen addition to CH 2 OH and CH 3 CHOH was estimated to be about 6 and 7%, respectively. The oxygen addition ratio to (CH 3 ) 2 COH was very low. The reaction mechanism is also discussed.
