In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Michael Morse of the University of Utah, together with his postdoctoral and graduate student researchers, will study the structure and boding in a series of transition metal silicides, early-late transition metal dimers (e.g. TiNi), transition dimer metal cations, and complexes of TiO+ cations with Lewis bases. These experiments will be carried out in a molecular beam or a cryogenically-cooled ion-trap. The molecules will be interrogated with a variety of laser spectroscopic methods. These molecular species are a challenge for current theoretical methods, thus these results will serve as useful benchmark systems to test new or improved computational chemistry methods. In addition, the species themselves are important models with which to build up useful models of technologically important materials -- from memory metals to titanium oxide photocatalysts. The young scientists working with Prof. Morse will use sophisticated lasers and vacuum apparatus, and will be well-trained for the technological workforce. Prof. Morse has trained a significant number of women scientists, and this track record is expected to continue.

在这个由化学系实验物理化学计划资助的奖项中，犹他州大学的Michael莫尔斯教授及其博士后和研究生研究人员将研究一系列过渡金属硅化物、早-晚过渡金属二聚体（例如TiNi）、过渡二聚体金属阳离子以及TiO+阳离子与刘易斯碱的络合物的结构和结合。 这些实验将在分子束或低温冷却离子阱中进行。 这些分子将用各种激光光谱方法进行分析。这些分子物种是对当前理论方法的挑战，因此这些结果将作为有用的基准系统来测试新的或改进的计算化学方法。 此外，这些物种本身也是重要的模型，可以用来建立从记忆金属到氧化钛光催化剂等重要技术材料的有用模型。 与莫尔斯教授一起工作的年轻科学家将使用先进的激光和真空设备，并将接受良好的技术培训。 莫尔斯教授培养了大批女科学家，预计这一记录将继续下去。
