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. ***

9300095 Eyler来自化学研究仪器计划的该奖项将帮助佛罗里达大学化学系购买傅里叶变换离子回旋共振质谱仪。 其研究依赖于傅里叶变换质谱的四名教师将从该仪器的收购中受益匪浅。 利用这一工具开展的研究项目包括：1）辉光放电多原子干扰的解析，2）单核和多核金属络合物离子的电喷雾FT-质谱研究，3）气相光活性金属络合物的光谱和热力学研究，4）金属和半导体簇的反应和光解离光谱，5）离子的激光形成和光解离; 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，用于测量分子离子的精确分子量。 它也可以用来获得关于气相中离子分子反应的非常详细的信息。 这些信息可以用来帮助确定原子组成，有时还可以确定分子的分子几何形状。 ***
