Construction of a Pulsed Beam Fourier Transform Microwave Spectrometer

该奖项来自化学研究仪器项目，将帮助卫斯理大学化学系获得一台脉冲束傅立叶变换微波光谱仪。该光谱仪将用于以下研究领域：稀有气体二卤化物与NF3和PF3配合物自由基和自由基复合物非常低的扭转障碍。含no6二聚物的结构。三聚体CO-H20-H20的结构微波光谱是一种测量由电磁波谱的远红外和微波区辐射引起的分子中纯旋转跃迁的技术。该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有用的数据，如键距、键角和偶极矩。

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.
