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

0443540马歇尔这个为期一年的奖项将支持何塞瓦莱，佛罗里达大学的学生在国家高场FT-ICR质谱设施由NSF支持的论文增强项目。 瓦莱先生的研究涉及使用红外光谱来区分不同类型离子的结构异构体。他专注于单一和小寡核苷酸。他将对荷兰等离子体物理研究所（FOM）的自由电子激光（FEL）设施进行两次长期访问。 瓦莱先生将与FOM研究所分子动力学项目的协调员何塞·奥门斯博士合作。 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）质谱仪与红外实验自由电子激光器（FELIX）耦合，以获得各类化学物质的气体离子红外（IR）光谱。 他将集中精力使用他获得的红外光谱来区分小分子芳烃的结构异构体，并将获得通过电喷雾电离形成的一个或多个多环芳烃离子的光谱。 他还将在巴黎大学Xi的第二个FTICR-FEL设施呆上一周。 他将为欧洲人提供与知识渊博的西班牙裔的互动，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.
