CAREER: Effects of Electronic Alignment in Laser Induced M-H2 and M-CH4 Reactions

北卡罗来纳a&t大学的Solomon Bililign在实验物理化学项目的支持下，研究了激光诱导金属-氢（M-H2）和金属-甲烷（M-CH4）反应中电子对准的影响。具体来说，他将研究金属原子的电子结构和电子轨道排列如何影响M-H2和M-CH4配合物的结构和化学反应性。远翼吸收光谱将扩展到研究瞬态双分子碰撞配合物的连续或散射状态，并研究LiH2、ZnH2和ZnCH4配合物中的退极化、化学猝灭和反应。这些研究的最终目标是获得一些金属与碳氢化合物的物理和化学结合的新的认识和详细的知识。与CAREER奖相关的教育活动包括社区学校的推广计划、与行业的联系、本科生的短期项目以及与本科生和研究生研究项目相关的课程开发。氢或碳氢键与金属原子位点的相互作用在均相或多相催化和有机金属化学等领域具有重要的意义。金属原子活化C-H键是化学中最重要和最基本的反应之一，可能导致效率更高、成本更低的催化反应。尽管这很重要，但我们对一些最简单的金属-原子-碳氢化合物反应还没有完全了解。这些详细的研究将为金属与碳氢化合物的物理和化学结合带来新的认识和详细的知识。此外，在一所历史悠久的黑人大学进行的这项研究项目将为培训和教育社会中代表性不足的成员提供非常基础的研究基础设施，并且在吸引非裔美国人和其他代表性不足的群体进行高级科学研究方面应该是非常有效的。

Solomon Bililign of North Carolina A&T University is supported by the Experimental Physical Chemistry Program in his studies on the effects of electronic alignment in laser-induced metal-hydrogen (M-H2) and metal-methane (M-CH4) reactions. Specifically, he will investigate how the electronic structure and electronic orbital alignment of a metal atom affects the structure and chemical reactivity of M-H2 and M-CH4 complexes. Far wing absorption spectroscopy will be extended to study the continuum or scattering state of a transient bimolecular collision complex and investigate depolarization, chemical quenching, and reaction in LiH2, ZnH2 and ZnCH4 complexes. The ultimate goal of these studies is to gain new understanding and detailed knowledge about the physical and chemical binding of some metals with hydrocarbons. The educational activities associated with this CAREER award include outreach programs to schools in the community, links to industry, short term projects for undergraduates and course development related to the research project both at the undergraduate and graduate levels. The interactions of hydrogen or carbon-hydrogen bonds with metal atom sites is of great interest and importance to areas such as homogeneous or heterogeneous catalysis and organometallic chemistry. C-H bond activation by metal atoms is one of the most important and basic reactions in chemistry and may lead to more efficient and less costly catalytic reactions. Despite this importance, we do not yet have a complete understanding of some of the simplest metal-atom-hydrocarbon reactions. These detailed studies will bring new understanding and detailed knowledge about the physical and chemical binding of metals with hydrocarbons. In addition, this research program at a historically black university will provide a very basic research infrastructure for the training and education of underrepresented members of society and should prove to be very effective in attracting African Americans and other underrepresented groups to advanced research in science.
