Matrix Isolation ESR Studies of Small Cluster Cation and Heavy Atom Diatomic Radicals; Laser Vaporization Methods

在化学学部物理化学项目的这个项目中，弗曼大学的朗·奈特将使用电子自旋共振（ESR）技术研究小簇阳离子自由基。利用x射线辐照和同步脉冲气体/脉冲激光汽化在低温基质中产生自由基。实验测量将产生电子结构信息，这些信息将与理论小组共享，以进行协作分析和解释。对一系列重原子双原子自由基的研究将有助于从头计算自旋密度的发展。从这项工作中获得的关于小的不稳定电离分子的信息将有助于确定制造半导体微电子元件的最佳条件，识别新的星际物种，以及了解地球上层大气中的反应。

In this project in the Physical Chemistry Program of the Chemistry Division, Lon Knight of Furman University will use electron spin resonance (ESR) techniques to study small cluster cation radicals. The radicals will be generated in low-temperature matrices using x-irradiation as well as synchronized pulsed gas/pulsed laser vaporization. The experimental measurements will yield electronic structure information which will be shared with theory groups for collaborative analysis and interpretation. Study of a series of heavy-atom diatomic radicals should aid in the development of ab initio spin-density calculations. Information obtained from this work on small unstable ionized molecules will be useful in determining the optimum conditions for fabricating semiconductor microelectronic components, in identifying new interstellar species, and in understanding reactions in the earth's upper atmosphere.
