Professor James C. Weisshaar is supported by a grant from The Physical Chemistry Program to study the structures and dynamics of polyatomic gas phase ions and radicals. The aim of this research project is a better understanding of how the electronic structures of transition metal species affects their reactivity. This area of research has important implications in the development of new chemical catalysts. Weisshaar will study the gas phase chemistry of transition metal ions and neutrals containing Sc, Ti, V, Cr, Mn, Co, etc., and their reactions with small organic molecules in a fast flow reactor. The transition metal ions will be prepared in selected electronic states using tunable dye laser ionization. This research extends the use of powerful gas phase chemical physics tools including dye lasers, molecular beams, and time-of-flight techniques into the regime of molecular systems of considerable complexity and genuine chemical interest.

James C. Weisshaar 教授获得物理化学项目的资助，用于研究多原子气相离子和自由基的结构和动力学。 该研究项目的目的是更好地了解过渡金属物质的电子结构如何影响其反应性。 该研究领域对新型化学催化剂的开发具有重要意义。 Weisshaar将研究包含Sc、Ti、V、Cr、Mn、Co等的过渡金属离子和中性物的气相化学，以及它们在快流反应器中与有机小分子的反应。 将使用可调谐染料激光电离以选定的电子态制备过渡金属离子。 这项研究将强大的气相化学物理工具（包括染料激光器、分子束和飞行时间技术）的使用扩展到相当复杂和真正具有化学意义的分子系统领域。
