This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Wesleyan University acquire a Pulsed Beam Fourier Transform Microwave Spectrometer. The spectrometer will be used in the following areas of research: 1. Rare Gas Dihalides 2. Complexes With NF3 and PF3 3. Free Radicals and Free Radical Complexes 4. Very Low Torsional Barriers 5. Structures of Dimer Complexes Containing NO 6. Structure of the Trimer Complex CO-H20-H20 7. Hydrogen Bonding With Ammonia Derivatives %%% Microwave spectroscopy is a technique which measures pure rotational transitions in a moleculer that are induced by radiation in the far infrared and microwave regions of the electromagnetic spectrum. This technique requires that the material be in the gaseous state and have a permanent dipole moment in the ground state. Useful data, such as bond distance, bond angle and dipole moment are obtained from microwave studies.

化学研究仪器项目的这一奖项将帮助卫斯理大学化学系获得一台脉冲光束傅里叶变换微波光谱仪。该光谱仪将用于下列领域的研究：1.稀有气体二卤化物2.与NF3和Pf3的络合物4.极低的扭转势垒5.含NO 6的二聚体络合物的结构CO-H20-H20的结构7.与氨衍生物的氢键%微波光谱学是一种测量分子在电磁光谱的远红外和微波区辐射诱导的纯转动跃迁的技术。这项技术要求材料处于气态，并在基态具有永久偶极矩。从微波研究中获得了键距、键角和偶极矩等有用数据。
