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.

在化学系物理化学计划的这个项目中，福尔曼大学的朗·奈特将使用电子自旋共振(ESR)技术来研究小团簇阳离子自由基。这些自由基将在低温基质中使用x射线以及同步脉冲气体/脉冲激光汽化产生。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算自旋密度计算的发展。从这项关于不稳定的电离小分子的工作中获得的信息将有助于确定制造半导体微电子组件的最佳条件，识别新的星际物种，并了解地球上层大气中的反应。
