Upgrade of Departmental X-Ray Facility

这份来自化学研究仪器和设施项目的合同将帮助麻省理工学院化学系购买一台r轴区域探测衍射仪、一台升级发电机和一台计算机。这种新的仪器将大大加强在以下几个领域的研究：(a)多金属-碳键、金属循环和催化反应；(b)高氧化态二氮配合物；(c)开环复分解聚合；(d)基本锝化学；(e)受体生物分子修饰；(f)不饱和分子与高应变有机配体的锆新世配合物；(g)低维氧化物；(h)三配位配合物的插入化学。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。得到的信息给出了给定分子的所有键距和键角的精确值，并给出了该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 will assist the Department of Chemistry at Massachusetts Institute of Technology in the purchase of a R-Axis Area detection diffractometer, an upgrade generator and the upgrade of a computer. This new instrumentation will enhance greatly research in a number of areas including the following: (a) Multiple Metal-Carbon Bonds, Metallacycles, and Catalytic Reactions, (b) High Oxidation State Dinitrogen Complexes, (c) Ring Opening Metathesis Polymerization (ROMP), (d) Fundamental Technetium Chemistry; (e) Modification of Receptor Biomolecules; (f) Zirconocene Complexes of Unsaturated Molecules and Highly Strained Organic Ligands; (g) Low Dimensional Oxides; and (h) Insertion Chemistry of Three-Coordinate Complexes. 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.
