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.

化学研究仪器和设施 (CRIF) 计划以及重大研究仪器 (MRI) 计划授予的这一奖项将使德克萨斯 A&M 大学化学系能够获得基于 CCD 的 X 射线衍射仪。 该设备将加强多个领域的研究，包括（1）研究二氧化碳的有机金属化学及其与催化过程的结合，从而产生有用的化学品； (2)大簇化合物的结构表征； (3) 新颖的、具有生物活性的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测量。获得的信息给出了给定分子的所有键距和键角的精确值，并且给出了有关分子相对于相邻分子的空间排列的准确信息。
