In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. L.-S. Wang of Washington State University will conduct a research program to investigate a variety or atomic clusters, chemisorbed clusters, and solution- phase species in the gas phase by photoelectron spectroscopy. Two techniques will be used to prepare these species: 1) Laser vaporization in a supersonic cluster source that produces atomic- and chemisorbed clusters; 2) use of an electrospray source that transports solution phase anions into the gas phase. The investigations will focus on small clusters of gold and other 4d and 5d transition metal clusters, on CO and O2 chemisorbed on well characterized gold clusters, on coinage metal cyanide clusters, and on the electronic structures chains of small clusters of cyanide molecules. In addition, studies will be undertaken of singly and multiply charged transition metal cyanide complexes and of multiply charged polynuclear ligated metal clusters. A search will be undertaken for gaseous zwitterions from amino acid-halide anion complexes. This research will be conducted with the assistance of postdoctoral research associates, and graduate and undergraduate students.

在这个由化学系实验物理化学计划资助的项目中，华盛顿州立大学的王L.-S·王教授将进行一项研究计划，用光电子能谱研究气相中的各种或原子团簇、化学吸附的团簇和溶液相物种。将使用两种技术来制备这些物质：1)在超音速团簇光源中进行激光汽化，产生原子和化学吸附的团簇；2)使用电喷雾光源，将溶液相负离子输送到气相中。研究将集中在金的小团簇和其他4d和5d过渡金属团簇，CO和O2化学吸附在表征良好的金团簇上，硬币金属氰化物团簇，以及氰化物小团簇的电子结构链。此外，还将对单电荷和多电荷过渡金属氰化物络合物以及多电荷多核连接金属簇合物进行研究。将从氨基酸-卤化物阴离子络合物中寻找气态两性离子。这项研究将在博士后助理研究员、研究生和本科生的协助下进行。
