The shape of small metal clusters is determined by forces intermediate between those of the isolated molecule and the extended solid. Particle shape plays an important role in surface interactions and catalytic behavior. This project will apply microwave-optical double resonance spectroscopy to determine the nature and extent of Jahn-Teller distortions in the vibronic spectra of small metal clusters. These experimental measurements will be a rigorous benchmark against which present theoretical calculations will be evaluated. This project is jointly supported by the Physics and Chemistry Divisions of NSF.

小金属团簇的形状是由介于孤立分子和延伸固体之间的中间力决定的。颗粒形状在表面相互作用和催化行为中起着重要作用。本项目将应用微波光学双共振光谱来确定小金属团簇振动光谱中的扬-泰勒扭曲的性质和程度。这些实验测量将是一个严格的基准，目前的理论计算将据此进行评估。本项目由美国国家科学基金会物理部和化学部联合支持。
