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·邦迪贝 (Vladimir Bondybey) 教授得到了物理化学项目的资助，用于研究极低温度下被困在稀有气体基质中的金属簇的结构和性质。这些信息对于开发用于研究金属簇的性质和模拟催化金属表面上发生的化学反应的精细理论方法具有无价的价值。使用脉冲激光的汽化技术将用于生成几乎任何材料的簇，包括大多数耐火元素和材料。以这种方式产生的团簇将在气相中以及作为捕获在惰性气体基质中的孤立团簇中进行研究。同核和异核金属以及半导体二聚体（例如氧化物、氮化物和碳化物）的光谱学将通过喷射中的激光诱导荧光进行研究。将通过使用傅里叶变换红外光谱仪监测激光诱导红外荧光来研究基质捕获的物质。
