In this project in the Physical Chemistry Program of the Chemistry Division, Muenter will study the radio frequency, microwave and infrared spectroscopy of weakly bound clusters. The study will lead to a better understanding of the intermolecular forces which play a role in many aspects of chemistry such as molecular conformations, solvent-solute interactions and transport properties. Minima of the intermolecular potential energy surfaces of cluster molecules will be determined by using high-resolution spectroscopy. Vibrational frequency shifts will provide the change in complex stability when a monomer mode is excited, while Stark effect measurements will provide a quantitative measure of mutual polarization of molecular charge distributions. The project will obtain radio frequency and microwave results from molecular beam resonance data.

在化学学部物理化学计划的这个项目中，Muenter将研究弱束缚团簇的射频、微波和红外光谱。这项研究将使我们更好地理解在化学的许多方面，如分子构象、溶剂-溶质相互作用和输运性质中起作用的分子间力。用高分辨率光谱法测定了簇分子的分子间势能面最小值。当单体模式被激发时，振动频移将提供复杂稳定性的变化，而斯塔克效应测量将提供分子电荷分布相互极化的定量测量。该项目将从分子束共振数据中获得射频和微波结果。
