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.

在这个项目中，由L.-S.教授的化学分部实验物理化学计划资助。华盛顿州立大学的王将通过光电学光谱法进行一项研究计划，以研究气相中的多样性或原子簇，化学簇和溶液相。 将使用两种技术来制备这些物种：1）在产生原子和化学吸附簇的超音速簇源中激光蒸发； 2）使用将溶液相位带入气相的电喷雾源。 研究将集中于金黄色和其他4D和5D过渡金属簇，在CO和O2化学上，在具有良好的金簇，硬币金属氰化物簇上以及氰化物分子小簇的电子结构链上进行的o2化学簇。 此外，将研究单一和多重电荷的过渡金属氰化物配合物和多重电荷的多核连接金属簇。将搜索来自氨基酸 - 卤化阴离子复合物的气态zwitter。 这项研究将在博士后研究伙伴以及研究生和本科生的协助下进行。
