Construction of a Pulsed Beam Fourier Transform Microwave Spectrometer

化学研究仪器计划的这一奖项将帮助卫斯理大学化学系获得脉冲束傅里叶变换微波光谱仪。该光谱仪将用于以下研究领域：1.稀有气体二卤化物2.与NF 3和PF 3的复合物3.自由基和自由基复合物4.非常低的扭转屏障5.含NO 6的二聚体配合物的结构。三聚体络合物CO-H2O-H2O的结构7.氨衍生物的氢键微波光谱是一种测量分子中纯转动跃迁的技术，这些跃迁是由电磁波谱的远红外和微波区域的辐射引起的。这种技术要求材料处于气态，并且在基态具有永久的偶极矩。通过微波研究得到了键距、键角和偶极矩等有用的数据。

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.
