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

本项目由化学学部实验物理化学项目资助，由李立生教授主持。华盛顿州立大学的王教授将开展一项研究计划，通过光电子能谱法研究各种原子团簇、化学吸收团簇和气相中的溶液相物种。两种技术将用于制备这些物质：1)激光汽化在超音速团簇源中产生原子和化学吸收团簇；2)使用电喷雾源将溶液阴离子输送到气相。研究将集中在金的小簇簇和其他4d和5d过渡金属簇簇、CO和O2在表征良好的金簇簇上的化学吸附、造币金属氰化物簇簇以及氰化物分子小簇簇的电子结构链上。此外，还将研究单电荷和多电荷的过渡金属氰化物配合物以及多电荷的多核连接金属团簇。将从氨基酸-卤化物阴离子络合物中寻找气态两性离子。本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.
