Probing the Electronic Structures of Atomic Clusters and Solution Phase Species in the Gas Phase

在本项目中，由化学系实验物理化学计划资助，L.- S.华盛顿州立大学的王将进行一项研究计划，通过光电子能谱法调查气相中的各种或原子团簇，化学吸附团簇和溶液相物种。 将使用两种技术来制备这些物质：1）在产生原子和化学吸附簇的超音速簇源中的激光蒸发; 2）使用将溶液相阴离子输送到气相中的电喷雾源。 调查将集中在小团簇的金和其他4D和5D过渡金属簇，CO和O2化学吸附在良好表征的金簇，钴金属氰化物簇，和氰化物分子的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配合物以及多电荷多核金属配位簇进行研究。将从氨基酸-卤化物阴离子复合物中寻找气态两性离子。 这项研究将在博士后研究助理，研究生和本科生的协助下进行。

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.
