Professor John Lombardi of City University of New York, City College is supported by the Experimental Physical Chemistry program to perform experimental studies on metal dimer binding. A specialized facility has been developed over the years at CUNY to mass select and deposit metal dimers and trimers in matrices and study them using Raman spectroscopy. This proposal seeks to expand previous work by including heteronuclear dimers, and to examine gold-M clusters (with M= La, Lu, Ce) which are relevant to the catalysis of proplyene oxide, an important industrial process. Collaboration with a theorist allows quantum chemical approaches to be brought to bear on the interpretation of these results on metal-metal binding. The gold clusters will also help theorists to understand relativistic effects. Increasing the importance of metal cluster studies is the recent effort by scientists to manipulate matter using nanotechnology. Metal clusters are also of interest in the field of catalysis. Understanding metal to metal binding is relevant to inorganic chemical synthesis and the production of new materials. CUNY City College is a Hispanic Serving Institution.

纽约城市大学城市学院的 John Lombardi 教授在实验物理化学项目的支持下进行金属二聚体结合的实验研究。 纽约市立大学多年来开发了一种专门的设施，用于在基质中大规模选择和沉积金属二聚体和三聚体，并使用拉曼光谱对其进行研究。 该提案旨在通过纳入异核二聚体来扩展之前的工作，并检查与氧化丙烯这一重要工业过程的催化相关的金-M簇（其中M= La、Lu、Ce）。 与理论家的合作使得量子化学方法能够应用于金属-金属结合的这些结果的解释。 金簇还将帮助理论家理解相对论效应。 科学家最近利用纳米技术操纵物质的努力日益增加了金属簇研究的重要性。 金属簇在催化领域也很受关注。 了解金属与金属的结合与无机化学合成和新材料的生产相关。 纽约市立大学城市学院是一所西班牙裔服务机构。
