Professor William Breckenridge of the University of Utah is supported by the Experimental Physical Chemistry program to perform experiments on the activation of C-H bonds in gaseous clusters containing metal centers. This proposal seeks to discover mechanisms by which C-H bond breaking occurs in gas phase clusters mimicking two situations: side-on interactions of metal electrons with C-H bonds as would occur in organometallic compounds, and C-H bond activation on the surfaces of metal oxides. The clusters will be studied using various laser probes such as laser-induced fluorescence, and multiphoton ionization spectroscopy. The problem of structure and dynamics in simple metal-hydrocarbon systems is made quite relevant in this proposal by the comparison to real world problems in catalysis. The breaking of C-H bonds is of great interest in a variety of important technological processes such as hydrocarbon cracking, catalysis, synthesis of chemicals from natural gas, hydrogenation and organic synthesis.

犹他州大学的William Breckenridge教授在实验物理化学计划的支持下，对含有金属中心的气态团簇中C-H键的活化进行了实验。 该提案旨在发现C-H键断裂在气相簇中发生的机制，模拟两种情况：金属电子与C-H键的侧边相互作用，如在有机金属化合物中发生的，以及金属氧化物表面上的C-H键活化。 将使用各种激光探针，如激光诱导荧光和多光子电离光谱研究团簇。 简单金属-烃体系的结构和动力学问题与催化领域的真实的世界问题相比，在这个建议中是非常相关的。 C-H键的断裂在许多重要的工艺过程中具有很大的意义，例如烃裂化、催化、由天然气合成化学品、氢化和有机合成。
