Instrumentation Upgrade for Molecular Structure Center

这份来自化学研究仪器和设施项目（CRIF）和多学科活动办公室（OMA）的合同将帮助印第安纳大学化学系通过获得CCD和CID系统来升级他们的分子结构中心。该设备将加强以下领域的研究：(1)Mn4簇的生物无机化学，(2)过渡金属簇化学，以及(3)异常不饱和，以及由此产生的非常弱配体的结合。x射线衍射仪用于对分子的完整三维结构进行精确的测量。所获得的信息给出了给定分子的所有键距和键角的精确值，并给出了分子相对于邻近分子的空间排列的准确信息。

This award from the Chemistry Research Instrumentation and Facilities Program (CRIF) and the Office of Multidisciplinary Activities (OMA) will help the Department of Chemistry at Indiana Ubniversity upgrade their Molecular structure Center by aquiring a CCD and CID systems. The equipment will enhance research in a number of areas including the following: (1) bioinorganic chemistry of Mn4 clusters, (2) transition metal cluster chemistry, and (3) unusual unsaturation, and consequent binding of very weak ligands. 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 the molecule relative to the neighboring molecules.
