US-Netherlands Dissertation Enhancement: Using Infrared Spectra to Distinguish Isomeric Ions

这项为期一年的奖励将支持佛罗里达大学学生Jose Valle在美国国家科学基金会支持的国家高场FT-ICR质谱设施的论文增强项目。Valle先生的研究包括使用红外光谱来区分不同种类离子的结构异构体。他主要研究单寡糖和小寡糖。他将对荷兰等离子体物理研究所（FOM）的自由电子激光（FEL）设备进行两次延长访问。Valle先生将与FOM研究所分子动力学项目协调员Jos Oomens博士合作。他将使用一种独特的仪器配置，将傅里叶变换离子回旋共振（FTICR）质谱仪与用于红外实验的自由电子激光器（FELIX）耦合在一起，从而获得气体离子的红外光谱，用于化学物质的分类。他将集中精力利用他得到的红外光谱来区分小糖的结构异构体，并将得到一个或多个由电喷雾电离形成的多环芳烃离子的光谱。他还将在巴黎第十一大学的第二个FTICR-FEL设施中度过一个星期。他将为欧洲人提供与知识渊博的西班牙人的互动，并更全面地了解美国高等教育中的文化多样性。

0443540MarshallThis one-year award will support the dissertation enhancement project of Jose Valle, a University of Florida student at the National High Field FT-ICR Mass Spectroscopy Facility supported by NSF. Mr. Valle's research involves using infrared spectra to distinguish between structural isomers of various classes of ions. He is concentrating on mono- and small oligo-saccharides. He will make two extended visits to a free electron laser (FEL) facility at the Institute for Plasma Physics (FOM) in The Netherlands. Mr. Valle will work with Dr. Jos Oomens, coordinator of the Molecular Dynamics program at the FOM institute. He will use a unique instrumental configuration that couples a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer to the free electron laser for infrared experiments (FELIX) to permit infrared (ir) spectra of gaseous ions to be obtained for classes of chemical species. He will concentrate on using the ir spectra he obtains to differentiate between structural isomers of small saccharides and will obtain the spectra of one or more polycyclic aromatic hydrocarbon ions formed by electrospray ionization. He will also spend a week at a second FTICR-FEL facility at the University of Paris XI. He will offer the Europeans interaction with a knowledgeable Hispanic and a more complete picture of the cultural diversity present in US higher education.
