Acquisition of a CCD-Based X-Ray Diffractometer

这份来自化学研究仪器和设施（CRIF）项目和主要研究仪器（MRI）项目的合同将使德州农工大学化学系获得一台基于ccd的x射线衍射仪。该设备将加强若干领域的研究，包括：(1)研究二氧化碳的有机金属化学，并将其纳入导致有用化学品的催化过程；(2)大簇化合物的结构表征；(3)新型生物活性天然产物的结构研究。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 (CRIF) Program and the Major Research Instrumentation (MRI) Program will enable the Department of Chemistry at Texas A&M University to acquire a CCD-based X-ray diffractometer. This equipment will enhance research in a number of areas including (1) investigations of the organometallic chemistry of carbon dioxide and its incorporation into catalytic processes leading to useful chemicals; (2) structural characterization of large cluster compounds; and (3) structural studies of novel, biologically active natural products. 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.
