In this project supported by the Experimental Physical Chemistry Program of the Chemistry Division, Lindsay and Lombardi will continue their study of the Raman spectra of mass-selected small metal cluster species in rare gas matrices in order to obtain structural information. The species of interest are produced by sputtering from a solid target, and the products are trapped in low temperature matrices and interrogated using absorption, excitation, fluorescence, and resonance Raman spectroscopy. Investigations of transition metal clusters will be followed by studies of alkaline earth species. The results of these studies will provide structural information that will aid in understanding the bonding properties of small metal clusters as a function of position in the periodic table. Such information is of interest to chemists and materials scientists who are trying to synthesize new metal-containing compounds for materials applications.

在该项目的支持下，在化学划分的实验物理化学计划的支持下，林赛和伦巴第将继续研究稀有气体基质中质量囊性小金属簇种的拉曼光谱，以获取结构信息。 感兴趣的物种是通过从固体靶标的溅射而产生的，并将产物捕获在低温矩阵中，并使用吸收，兴奋，荧光和共振拉曼光谱法对其进行询问。 对过渡金属簇的研究将进行碱性地球物种的研究。 这些研究的结果将提供结构信息，以帮助理解小型金属簇的键合特性，这是元素周期表中位置的函数。 这些信息引起了化学家和材料科学家的关注，他们试图为材料应用合成新的含金属化合物。
