Spectroscopy of, and Dynamics Within, Atom.(Rare-Gas)n and Atom.(Molecule)n van der Waals Complexes

在这个项目中，在实验物理化学计划的 布雷肯里奇的化学部将研究光谱学， MXn型货车德瓦耳斯团簇的动力学，其中M是原子， 通常为第II、III或IV族金属，X为稀有气体原子或 分子。 这些复合物将在超音速喷气机中制造， 特征在于激光诱导荧光（LIF），共振双光子 光电离光谱（R2 PI）和激光泵浦-探测“作用” 谱 这项研究计划的一个目标是更好地了解 分子中原子和C-H键之间的电子相互作用， 原子电子态的函数。 特别有趣的是 物理和化学相互作用之间的过渡区。 一 本工作的应用是作为催化C-H键活化的模型 在固体金属氧化物位点。

In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Breckenridge will examine the spectroscopy and dynamics of van der Waals clusters of the type MXn, where M is an atom, typically a Group II, III or IV metal, and X is a rare-gas atom or a molecule. The complexes will be made in a supersonic jet and will be characterized by laser-induced fluorescence (LIF), resonant two-photon photoionization spectroscopy (R2PI), and laser pump-probe `action` spectroscopy. One goal of this research program is to understand better the nature of electronic interactions between atoms and C-H bonds in molecules as a function of atomic electronic state. Particularly interesting will be the transition region between physical and chemical interactions. One application of this work is as a model for catalytic C-H bond activation at solid metal-oxide sites.
