The yields of the ring cleavage products glyoxal, methylglyoxal, and biacetyl from the reactions of OH radicals with benzene, toluene, o-, m-, and p-xylene, and 1,2,3-, 1,2,4-, and 1,3,5-trimethylbenzene in the presence of parts per million concentrations of NO have been determined in 1 atm of air at 298 +/- 2 K using in situ long-path-length Fourier transform infrared absorption spectroscopy and differential optical absorption spectroscopy with supplementary gas chromatographic analyses. These data are important inputs to chemical models of the NO/sub x/-air photoxidations of these aromatic hydrocarbons. 25 references, 3 figures, 1 table.
