Rate constants for the reactions of OH radicals with CH2=CHNO2, CH2=CH-CH2NO2 and c-C6H9NO2 have been determined at 298 ± 2 K and a total pressure of 1 atm. Rate data for the reaction of OH radicals with CH2=CH2, CH2=CH-CH3 and c-C6H10 were also obtained for comparison purposes. The OH rate data for all the compounds except c-C6H9NO2 were obtained using the absolute technique of pulse radiolysis combined with kinetic UV spectroscopy. Water-argon mixtures were irradiated and the OH kinetics recorded by following the transient light absorption at 309 nm. The rate constant for the OH + c-C6H9NO2 reaction was derived using a conventional photolytic relative-rate method. The results are discussed in terms of structure-reactivity relationships.
