Molecular Structure and Vibrational Potential Energy Surfaces in Ground and Excited Electronic States

这项研究是实验物理化学计划的一部分，使用红外、拉曼和荧光光谱技术来获得环状和双环分子的能级和势能面。其他研究领域包括液体中的分子间相互作用和金属团簇的振动能级。这些研究将阐明所研究体系的基态和激发态中的化学键和分子内力。远红外光谱、拉曼光谱和荧光光谱将用于研究环、四元环、五元环和六元环、双环物种和环己烯类分子的能级。这些数据将被解释为产生这些物种的势能面。为了了解分子间的相互作用，将使用拉曼差分光谱在液体的同位素混合物中获得微小的频移。为了确定这些分子的振动力场，将获得典型金属团簇的红外和拉曼矩阵隔离光谱。

This research, part of the Experimental Physical Chemistry Program, uses the techniques of infrared, Raman, and fluorescence spectroscopy to obtain energy levels and potential energy surfaces for cyclic and bicyclic molecules. Other areas of study include intermolecular interactions in liquids and vibrational energy levels of metal clusters. These studies will elucidate chemical bonding and intramolecular forces, both in the ground and excited states of the systems studied. Far infrared, Raman and Fluorescence spectroscopy will be used to study the energy levels of cyclic, four, five and six membered rings, bicyclic species and cyclohexene-like molecules. These data will be interpreted to yield potential energy surfaces for these species. Raman difference spectroscopy will be used to obtain small frequency shifts in isotopic mixtures of liquids in order to understand intermolecular interactions. Infrared and Raman matrix isolation spectra will be obtained for prototypical metal clusters in order to determine the vibrational force fields for these molecules.
