Rate consts. for the reactions of the hydroxycyclohexadienyl (HCHD) radical, the adduct of the OH + benzene reaction, with NO2 (1) and NO (2) in the gas phase have been detd. at 298 K using long-path cw UV laser absorption to monitor HCHD. The rate consts. are found to be k1 = (8.5 +- 2.1) * 10-12 cm3/s and k2 = (1.0 +- 0.5) * 10-12 cm3/s. The apparent rate coeff. for reaction (2) is only slightly influenced by addn. of O2.
