In this award, funded by the Chemical Structure, Dynamics and Mechanisms Program of the Chemistry Division, Prof. Timothy C. Steimle of Arizona State University and his postdoctoral fellows, graduate, and undergraduate research students will study the high-resolution optical and microwave spectroscopy of metal-containing small molecules. A systematic study of metal mono- and dihydrides (MH, MH2), monofluorides (MF) and hydroxides (MOH) for the early transition metal group (scandium to copper) will be performed, with particular emphasis on the determination of electric and magnetic dipole moments, and magnetic hyperfine interactions. This study will reveal insights into the nature of chemical bonding in metal containing molecules, and allow for an assessment of the reliability of computational methodologies. Metal containing molecules such as the di- and tri-atomic systems targeted in this research represent model for understanding a variety of important reactions involving metals, including catalytic reactions. A second effort will focus on high atomic number diatomic metal halides and oxides which are the focus of parity non-conservation investigations. Parity non-conservation is a topic that concerns the fundamental symmetry properties of the universe and the effects are greatly enhanced in polar high atomic number metal containing diatomic molecules.In addition to the aforementioned broader scientific applications of the proposed research to cutting-edge experiments in exciting areas of modern physics research, Prof. Steimle maintains a small but diverse research group, with whom he works closely to train in modern instrumental methods and sophisticated quantum mechanics. The group benefits from a number of collaborations -- both foreign as well as domestic -- which provides his group members with valuable interdisciplinary experience that crosses international borders.

在该奖项中，由化学结构，动力学和机制计划资助，亚利桑那州立大学的Timothy C. Steimle教授及其博士后研究员，毕业生和本科研究生将研究金属含量小分子的高分辨率光学和微波光谱。对早期过渡金属组（到铜的scandium to Copper）的系统研究（MH，MH2），单氟化物（MF）和氢氧化物（MOH）（MOH）的系统研究将尤其强调，并特别强调了电力和磁性二极管矩和磁性超富相互作用的确定。这项研究将揭示对含有分子金属化学键合的性质的见解，并允许评估计算方法的可靠性。该研究中针对的含有分子的金属（例如二 - 原子系统）代表了了解涉及金属（包括催化反应）的各种重要反应的模型。第二次努力将集中于高原子数硅质金属卤化物和氧化物，这是平等性不保守研究的重点。不保守均衡是一个涉及宇宙的基本对称性的话题，并且在极地高原子数金属中，效果得到了极大的增强和精致的量子力学。该小组受益于许多合作 - 外国和国内 - 为他的小组成员提供了跨越国际边界的宝贵跨学科经验。
