The reaction of CH{sub 2}OH with O{sub 2}, NO, and NO{sub 2} has been studied using pulse radiolysis to generate the radicals and ultraviolet absorption to observe the kinetics. Rate constant values of (0.88 {plus minus} 0.02) {times} 10{sup {minus}11}, (2.5 {plus minus} 0.02) {times} 10{sup {minus}11}, and (2.3 {plus minus} 0.4) {times} 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} have been measured at room temperature and 1 atm pressure for the O{sub 2}, NO, and NO{sub 2} reactions, respectively. Absorptions due to long-lived or stable products were observed in the same spectral region. A simple analysis of these observations suggests that formation of an adduct may dominate in the reaction of CH{sub 2}OH with NO and NO{sub 2} but that this process accounts for only a minor route in the O{sub 2} reaction.
