Purchase of an X-Ray Diffractometer

9309690巴顿化学研究仪器项目的这一奖项将有助于密苏里大学圣彼得堡分校化学系的研究。路易购买了一台X射线衍射仪和一个相关的数据分析系统。这一新仪器将极大地加强一些领域的研究，包括：DPPC桥联双铂配合物的结构和机理研究；五硼烷(9)和六硼烷(10)的IV族衍生物的结构研究；金属有机分子电子和结构的高分辨率X射线衍射分析；立体选择性键形成中的手性膦酰胺；以及硅三环和硅-硅键的结构研究。X射线衍射仪用于对分子的全部三维结构进行精确和精确的测量。得到的信息给出了给定分子的所有键距和键角的精确值，并提供了关于该分子相对于邻近分子的空间排列的准确信息。***

9309690 Barton This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at the University of Missouri--St. Louis in the purchase of an x-ray diffractometer and an associated data analysis system. This new instrumentation will enhance greatly research in a number of areas including the following: Structural and mechanistic studies of Dppc-bridged diplatinum complexes; Structural studies of group IV derivatives of pentaborane(9) and hexaborane(10); The use of high resolution diffraction x-ray analyses of the electronic and structural properties of organometallic molecules; Chiral phosphonamides in stereoselective bond formations; and Structural studies of silicon tricycles and silicon-silicon bonds. %%% The x-ray diffractometer is used to make accurate and precise measurements of the full three-dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of that molecule relative to the neighboring molecules. ***
