By using photoionization mass spectrometry, shock tube, and laser induced fluorescence techniques, several important elementary reactions related to low tomperature oxidation mechanism of hydrocarbons have been investigated. The types of reactions studied in this project are ; (1) direct abstraction of hydrogen atoms by O(^3P) from a series of C1-CO alkanes, (2) thermal decomposition and isomerization processes of C2-CO alkyl radicals, (3) thermal decomposition of butylperoxi radicals, and thermal decomposition, consumption, and production of alkoxi radicals.Not only the rate constants for individual reactions, the general rate laws for the site selectivity for primary secondary and tertiary sites of C-H bond, branching fractions for the products, and the pressure fall-off effects are investigated systematically. They are the first direct investigations of examination for the reactivity of a series of alkanes, alkyl alkylperoxi, and alkoxiradicals.

通过使用光离子质谱，冲击管和激光诱导的荧光技术，已经研究了几种与低质体氧化机制有关的重要基本反应。该项目中研究的反应类型是； （1）从一系列C1-co烷烃中通过O（^3p）直接抽取氢原子，（2）C2-CO烷基自由基的热分解和异构化过程，（（3））热分解丁基氧基自由基的热分解，以及丁基分解率，均一率，均无量的量级，均应量度，并产生烷基的速率。对于C-H键的初级二级和三级位点，系统地研究了产品的分支分数以及压力下降效应。它们是对一系列烷烃，烷基烷基氧基和烷基Roxiradicals的反应性检查的首次直接研究。
