Raman Spectroscopy of Mass-Selected Metal Clusters

在这个由化学系实验物理化学项目支持的更新奖项中，约翰·R·纽约城市学院的隆巴迪将进行研究，研究质量选择的过渡金属簇的共振拉曼光谱。 待研究的系统包括杂原子金属二聚体，以及三聚体和四聚体。 这些系统中的许多作为工业过程的潜在催化剂是令人感兴趣的。 从这些光谱研究的结果也将被用来推断这些系统中的键合信息。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体系，并提供基准实验值，以测试处理重金属原子的计算方法。 此外，他们将提供宝贵的研究经验，学生来自传统上在化学代表性不足的群体。

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.
