Spectroscopic Studies of Clusters and Their Chemistry

来自俄亥俄州立大学的Vladimir Bondybey教授得到了物理化学项目的资助，研究低温下稀有气体基质中金属团簇的结构和性质。这些信息对于研究金属簇的性质和模拟在催化金属表面上发生的化学反应的精炼理论方法的发展是无价的。使用脉冲激光的汽化技术将用于产生几乎任何材料的团簇，包括大多数难熔元素和材料。以这种方式产生的团簇将在气相和作为被困在惰性气体基质中的孤立团簇进行研究。利用激光诱导的荧光，研究了同核和异核金属以及半导体二聚体（如氧化物、氮化物和碳化物）的光谱。利用傅里叶变换红外光谱仪监测激光诱导的红外荧光，研究基质捕获物。

Professor Vladimir Bondybey from The Ohio State University is supported by a grant from The Physical Chemistry Program to study the structures and properties of metal clusters trapped in rare gas matrices at very low temperatures. This information is invaluable in the development of refined theoretical methods for studying the properties of metal clusters and for modeling chemical reactions which occur on catalytic metal surfaces. Vaporization techniques using pulsed lasers will be used to generate clusters of virtually any material including most refractory elements and materials. Clusters produced in this manner will be studied in the gas phase and as isolated clusters trapped in inert gas matrices. Spectroscopy of both homonuclear and heteronuclear metals and semiconductor dimers such as oxides, nitrides, and carbides will be studied by laser induced fluorescence in the jet. The matrix trapped species will be studied by monitoring the laser induced infrared fluorescence using a Fourier Transform infrared spectrometer.
