Purchase of a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer

这份来自化学研究仪器项目的合同将帮助佛罗里达大学化学系购买一台傅里叶变换离子回旋共振质谱仪。四个教师的研究依赖于傅里叶变换质谱将大大受益于该仪器的收购。将利用这一工具进行的研究项目包括：1)辉光放电多原子干扰的分辨，2)单核和多核金属配合物离子的电喷雾ft -质谱研究，3)气相光活性金属配合物的光谱和热力学研究，4)金属与半导体团簇的反应和光解光谱，5)离子的激光形成和光解，6)吡啶离子的形成和双分子反应性。傅里叶变换质谱仪具有极高的质量分辨率，可用于精确测量分子离子的分子量。它也可以用来获得气相中离子分子反应的非常详细的信息。这些信息可用于帮助确定分子的原子组成，有时还可用于确定分子的分子几何形状。＊＊＊

9300095 Eyler This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at the University of Florida in the purchase of a Fourier transform ion cyclotron resonance Mass Spectrometer. Four faculty members whose research is dependent upon Fourier transform mass spectroscopy will greatly benefit from the acquisition of this instrument. Research projects to be carried out with this instrument include: 1) Resolution of glow discharge polyatomic interferences, 2) Electrospray FT-mass spectral studies of mono-nuclear and polynuclear metal complex ions, 3) Spectroscopic and thermodynamic studies of gas-phase photoactive metal complexes, 4) Reactions of metal and semiconductor clusters and photodissociation spectroscopy, 5) Laser formation and photodissociation of ions, 6) Formation and bimolecular reactivity of pyridinium ions. %%% A Fourier transform mass spectrometer is capable of extremely high mass-resolution and is used to measure the precise molecular weight of a molecular ion. It may also be used to obtain highly detailed information about ion molecule reactions in the gas phase. This information may be used to help determine the atomic composition and, sometimes, the molecular geometry of a molecule. ***
