Purchase of a CCD-Based X-ray Diffractometer

根据化学研究仪器和设施（CRIF）项目的拨款，马萨诸塞大学阿默斯特分校的化学系将获得一台基于ccd的x射线衍射仪。该设备将加强若干领域的研究，包括：a)合成新型烯烃聚合催化剂；B)无机/有机复合材料的仿生固态合成；C)稳定自由基及相关前体物质的晶体结构；D)金属生物分子和合成模型方法的研究；E)利用功能化二氨基三嗪进行晶体工程；f)使用“晶体工程”设计和构建固态材料。x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，并提供分子相对于邻近分子的空间排列的准确信息。

With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Massachusetts in Amherst will acquire a CCDbased X-ray diffractometer. This equipment will enhance research in a number of areas including the following: a) synthesis of novel olefin polymerization catalysts; b) biomimetic solid-state syntheses of inorganic/organic composites; c) crystal structures of stable radicals and related precursor substances; d) studies of metallobiomolecules and synthetic model approaches; e) crystal engineering using functionalized diaminotriazines; and f) the design and construction of solid state materials using 'crystal engineering'.The X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules.
