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.

俄亥俄州立大学的弗拉基米尔·邦迪比（Vladimir Bondybey）教授得到了物理化学计划的赠款，以研究在非常低温下被困在稀有气体基质中的金属簇的结构和特性。在研究金属簇的特性以及建模发生在催化金属表面上的化学反应的特性的理论方法的发展中，此信息是无价的。使用脉冲激光器的汽化技术将用于生成几乎所有材料的簇，包括大多数难治性元素和材料。以这种方式产生的簇将在气相中进行研究，并作为孤立的簇被困在惰性气体基质中。同核和异核金属以及半导体二聚体（例如氧化物，硝酸盐和碳化物）的光谱将通过激光诱导的速度研究。将通过使用傅立叶变换红外光谱仪监测激光诱导的红外荧光来研究基质捕获的物种。
