Studies of Chemisorbed Species on Cluster Surfaces

在实验物理化学计划和化学仪器计划的支持下，斯莫利教授继续他对小金属团簇离子的性质、光化学和表面化学的研究。他对碳团簇的研究直接关系到在从火焰到星际介质的各种条件下碳的凝聚和存活以及碳烟的形成。对小金属团簇表面反应的研究应该刺激(并为其提供严格的试验基础)发展分子水平表面现象细节的第一性原理理论方法。质量选择团簇离子的研究将包括：(1)用串联飞行时间质谱仪研究冷团簇的光学光谱；(2)负团簇的紫外光电子能谱；(3)傅里叶变换离子回旋共振研究磁场中团簇离子的表面化学和光物理。

With support from the Experimental Physical Chemistry Program and the Chemistry Instrumentation Program, Professor Smalley is continuing his investigations of the properties, photochemistry, and surface chemistry of small metallic cluster ions. His studies of carbon clusters are directly relevant to the understanding of carbon condensation and survival and soot formation under conditions ranging from flames to the interstellar medium. Studies of surface reactions on small metal clusters should stimulate (and provide a rigorous testing ground for) the development of first-principles theoretical approaches to the molecular level details of surface phenomena. The research on mass-selected cluster ions will include (1) optical spectroscopy of cold clusters using tandem time-of-flight mass spectrometry, (2) ultraviolet photoelectron spectroscopy of negative clusters, and (3) Fourier transform ion cyclotron resonance studies of the surface chemistry and photophysics of cluster ions trapped in a magnetic field.
