This research project, supported by the Analytical and Surface Chemistry Program, is concerned with the surface chemistry of small alkyl radicals on well characterized surfaces. Professor Stair has developed a novel radical source which is used to produce and deposit alkyl radicals on well characterized solid surfaces of molybdenum and iron. The oxidative and radical coupling chemistry of the adsorbed species will be explored using a variety of ultra-high vacuum spectroscopic probes. Studies of the detailed dynamics of radical adsorption will also be carried out. %%% One approach to the understanding of the complex surface chemistry of hydrocarbon catalysis is to investigate the detailed surface chemistry of possible reaction intermediates. This research project uses this approach by preparing radical alkyl intermediates and depositing them on a well characterized surface. The chemistry of these intermediates is then examined, providing a detailed understanding of the mechanism of hydrocarbon catalysis.

该研究项目在分析和表面化学计划的支持下与表面良好的表面上的小烷基自由基的表面化学有关。 阶梯教授开发了一种新的自由基，该来源用于在钼和铁的固体表面上产生和沉积烷基自由基。 将使用各种超高真空光谱探针探索吸附物种的氧化和自由基耦合化学。 还将对自由基吸附的详细动力学进行研究。 %% %%理解烃催化的复杂表面化学的方法是研究可能反应中间体的详细表面化学。 该研究项目通过制备自由基烷基中间体并将其沉积在表面良好的表面上，使用这种方法。 然后检查这些中间体的化学性质，从而详细了解碳氢化合物催化的机理。
