• Absolute rate constants were measured for several reactions of ground-state oxygen atoms at 296±2 K. The pulse-radiolysis of O<SUB>2</SUB>, CO, or CO<SUB>2</SUB> in the He diluent was used to produce oxygen atoms, and the atomic concentration was monitored by the resonance absorption. The measurements were made in the pressure range from 50 to 950 Torr (1 Torr \simeq133.3 Pa). The rate constants thus obtained were (2.5±0.3)×10<SUP>−34</SUP> for O+O<SUB>2</SUB>+He and (1.0±0.2)×10<SUP>−35</SUP> for O+CO+He in units of cm<SUP>6</SUP> molecule<SUP>−2</SUP> s<SUP>−1</SUP> (1 cm<SUP>6</SUP> molecule<SUP>−2</SUP> s<SUP>−1</SUP>\simeq3.626×10<SUP>35</SUP> m<SUP>6</SUP> mol<SUP>−2</SUP> s<SUP>−1</SUP>). For simple olefins, the following bimolecular rate constants (<I>k</I>⁄10<SUP>−12</SUP> cm<SUP>3</SUP> molecule<SUP>−1</SUP> s<SUP>−1</SUP>) were obtained: Ethylene (1.0±0.2), propene (4.7±0.3), 1-butene (4.7±0.5), <I>trans</I>-2-butene (23±3), <I>cis</I>-2-butene (20±3), 2-methylpropene (17±2), 2-methyl-2-butene (55±5), 1,3-butadiene (20±2), (1 cm<SUP>3</SUP> molecule<SUP>−1</SUP> s<SUP>−1</SUP>\simeq6.022×10<SUP>17</SUP> m<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP>). These rate constants were in fair agreement with the literature values.
