Acquisition of X-Ray Diffractometer System

x射线晶体学技术是测定小多肽和复杂金属团簇等多种化合物分子结构的有力工具。当与最新的计算机软件相结合时，这项技术变得非常容易实施。x射线晶体学仪器的获得显著提高了化学家开展前沿研究的能力。基恩州立大学化学系将使用化学共享仪器计划的RUI奖来帮助获得x射线衍射仪。该仪器将用于加强本系和邻近机构的系的研究，并改进基恩州立大学的本科化学课程。此次收购将加强的研究领域包括：1)铜激光染料簇的结构研究2)视黄酰基席夫碱聚氨酯弹性体体系的结构研究与分子模拟3)含全氟有机配体的过渡金属配合物5)手性过渡金属-烯烃配合物：在有机合成中的应用6)新型钼（II）烯丙基化合物7)液晶聚合物体系的模型化合物8)ın！（9,10）炭疽- cenophanes(9)四氮大环配体的过渡金属配合物。

The technique of X-ray crystallography is a powerful tool for the determination of the molecular structure of compounds as diverse as small polypeptides and complex metal clusters. When combined with the latest computer software, the technique is becoming remarkably easy to put into practice. The acquisition of X-ray crystallographic instrumentation markedly improves the ability of chemists to carry out frontier research. The Department of Chemistry at Keene State College will use this RUI award from the Chemistry Shared Instrumentation Program to help acquire an X-ray diffractometer. The instrument will be used to enhance research in the Department and in the Departments of neighboring institutions and to improve the undergraduate chemistry curriculum at Keene State. Among the areas of research to be enhanced by the aquisition are: 1) Structural investigations of copper (I)-laser dye clusters 2) Structure studies and molecular modeling of retinyl Schiff base-urethane elastomer systems 3) Transition metal complexes containing perfluorinated organic ligands 4) Cages, heterocycles and oligomers from coordinated phosphines 5) Chiral transition metal-olefin complexes: application to organic synthesis 6) New molybdenum (II) allyl compounds 7) Model compounds of liquid crystal polymer systems 8) Structural and conformational studies of ın!(9,10) anthra- cenophanes 9) Transition metal complexes of tetraaza macrocyclic ligands.
