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教授得到实验物理化学计划的支持，对金属二聚体结合进行实验研究。 多年来，纽约市立大学开发了一种专门的设备，用于在基质中大量选择和存款金属二聚体和三聚体，并使用拉曼光谱法对其进行研究。 该建议旨在扩大以前的工作，包括杂原子二聚体，并检查金M簇（与M= La，Lu，Ce），这是相关的催化氧化丙烯，一个重要的工业过程。 与理论家的合作使量子化学方法能够解释金属-金属结合的这些结果。 金团簇也将帮助理论家理解相对论效应。 增加金属簇研究的重要性是科学家最近努力利用纳米技术操纵物质。 金属簇合物在催化领域也是令人感兴趣的。 了解金属与金属的结合与无机化学合成和新材料的生产有关。 CUNY City College是一所西班牙裔服务机构。
