With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Rochester will upgrade an X-ray diffractometer with a more sensitive detector, a more intense beam, low temperature apparatus and video microscope. This equipment will enhance research in a number of areas including the following: a) three-coordinate, paramagnetic complexes of iron, cobalt, and nickel; b) activation of strong bonds; c) luminescent complexes of platinum and gold; and d) stereoselective total synthesis of natural products and development of synthetic organic methodology. 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. These studies will have an impact in a number of areas, in particular synthetic organic chemistry.

在化学研究仪器和设施（CRIF）计划的支持下，罗切斯特大学化学系将升级一台X射线衍射仪，配备更灵敏的探测器、更强的光束、低温装置和视频显微镜。这一设备将加强若干领域的研究，包括：（a）铁、钴和镍的三配位顺磁性络合物;（B）强键的活化;（c）铂和金的发光络合物;（d）天然产品的立体选择性全合成和有机合成方法的发展。X射线衍射仪可以精确测量分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻分子的空间排列的准确信息。这些研究将在许多领域产生影响，特别是合成有机化学。
