In this renewal award, supported by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. John R. Lombardi of the City College of New York will conduct research studying the resonance Raman spectra of mass-selected transition metal clusters. The systems to be studied include heteronuclear metal dimers, as well as trimers and tetramers. Many of these systems are of interest as potential catalysts for industrial processes. Results from these spectroscopic studies will also be used to infer information about the bonding in these systems. The mass-selected molecules will be embedded in rare gas matrices at low temperatures or deposited onto semiconductor quantum dot arrays. These studies will help shed light on certain catalytic systems, as well as provide benchmark experimental values with which to test computational methods dealing with heavy metal atoms. In addition, they will provide valuable research experience to students coming from groups traditionally underrepresented in chemistry.

在该续奖中，在化学系实验物理化学项目的支持下，纽约城市学院的John R. Lombardi教授将开展质量选择过渡金属簇的共振拉曼光谱研究。 要研究的系统包括异核金属二聚体以及三聚体和四聚体。 其中许多系统作为工业过程的潜在催化剂而受到关注。 这些光谱研究的结果也将用于推断有关这些系统中键合的信息。经过质量选择的分子将在低温下嵌入稀有气体基质中或沉积在半导体量子点阵列上。 这些研究将有助于阐明某些催化系统，并提供基准实验值来测试处理重金属原子的计算方法。 此外，他们还将为来自传统化学领域代表性不足的群体的学生提供宝贵的研究经验。
