Thermochemical and Kinetics Studies of Important Radicals

Sidney W. Benson教授获得了理论与计算化学项目的资助，研究原子-自由基和自由基-自由基反应的热力学和动力学。该研究结果将为烃类燃烧和大气化学的建模提供重要的输入。本森将采用极低压反应器（VLPR）技术来研究烷基自由基与氧在广泛温度范围内的反应动力学。将收集有关这些反应的充分数据，以区分加成机制和再分解机制。此外，还将研究涉及卤代烃的原子自由基反应动力学。这些卤代烃是在氯原子与卤代烃自由基的各种自由基反应中形成的。

Professor Sidney W. Benson is supported by a grant from the Theoretical and Computational Chemistry Program to study the thermodynamics and kinetics of atom-radical and radical-radical reactions. The results of this research should provide important input for modeling hydrocarbon combustion and atmospheric chemistry. Benson will employ the Very Low Pressure Reactor (VLPR) technique to invistigate the kinetics of the reaction of alkyl radicals with oxygen over a wide range of temperatures. Sufficient data will be collected on these reactions to distinguish between an addition mechanism and a metathesis mechanism. In addition the kinetics of atom-radical reactions involving halocarbenes will be studied. These halocarbenes are formed in various radical reactions involving atomic chlorine with halogenated hydrocarbon free radicals.
