研究了在20 vol. %（质量分数）臭氧氧化乙烯（ET）、丙烯（PR）、顺式-2-丁烯（CB）、反式-2-丁烯（TB）、2，3-二甲基-2-丁烯（TME）和异戊二烯（ISP）时产生的OH自由基。O2已在1巴总压下在黑暗的玻璃反应器中测定。所形成的羟基自由基被清除的过量的CO添加到系统中。存在的O2将该反应中形成的H原子转化为HO 2。从通过FTIR的CO2生成的增加的测量中，OH形成产率被确定为每分子反应的臭氧分别为0.08（ET）、0.18（PR）、0.17（CB）、0.24（TB）、0.36（TME）和0.19（ISP）。OH测定的综合误差估计为<10%。John Wiley & Sons，Inc.
The OH radical yields generated in the ozonolysis of ethene (ET), propene (PR), cis-2-butene (CB), trans-2-butene (TB), 2,3-dimethyl-2-butene (TME), and isoprene (ISP) in the presence of 20 Vol.% O2 have been determined in a darkened glass reactor at 1 bar total pressure. The hydroxyl radicals formed were scavenged by an excess of CO added to the systems. The O2 present converted H atoms formed in this reaction into HO2. From measurements of the increase in CO2 generation by FTIR the OH formation yields were determined to be 0.08 (ET), 0.18 (PR), 0.17 (CB), 0.24 (TB), 0.36 (TME), and 0.19 (ISP), respectively, per molecule of reacted ozone. The combined error in the OH determinations is estimated to be <10%. © 1997 John Wiley & Sons, Inc.
