RUI: Gas Phase Reactions of Excited State Transition Metal Ions

中央阿肯色州大学的William Taylor教授得到实验物理化学计划的支持，对气相中与碳氢化合物络合的金属离子进行实验研究。 过渡金属经常被用作活化烃的催化剂，但人们并不了解反应性如何取决于金属的电子状态。 该提案旨在研究几种晚期第一、第二和第三行过渡金属离子与小烃的反应性，作为金属电子激发的函数。 低能离子漂移池和电子态色谱方法将用于研究铂离子和甲烷等反应体系。 这一提议的成功结果将是过渡金属反应性的模型，这将允许设计更好的催化剂。 在这个模型中的重要问题包括考虑电子组态和电子自旋守恒。从较大的金属提出的新结果将解释在光PI的第一行chemical.Transition金属离子的先前结果有能力打破sigma键，和这个属性是最有用的烃转化为其他化合物。 了解这一过程的机理将允许设计新的和更好的催化剂用于化学合成和石油工业。

Professor William Taylor of the University of Central Arkansas is supported by the Experimental Physical Chemistry program to perform experimental studies on metal ions complexed with hydrocarbons in the gas phase. Transition metals are frequently used as catalysts for activating hydrocarbons, but it is not understood how reactivity depends on the electronic state of the metal. This proposal seeks to study the reactivity of several late first-, second- and third-row transition metal ions with small hydrocarbons as a function of electronic excitation of the metal. Low energy ion drift cell and electronic state chromatographic methods will be used to study reactive systems such as platinum ion and methane. A successful outcome of this proposal would be a model of transition metal reactivity that would allow better catalysts to be designed. Important issues in this model include considerations of electron configuration and conservation of electron spin. New results from the larger metals proposed will be interpreted in the light of the PI's previous results on first row chemistry.Transition metal ions have the ability to break sigma bonds, and this property is most useful in converting hydrocarbons to other compounds. Understanding the mechanism of this process will allow design of new and better catalysts for use in chemical synthesis and the petroleum industry.
