With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Virginia Polytechnic Institute and State University will acquire a X-ray diffractometer with CCD detector for small molecule diffractometry. This equipment will enhance research in a number of areas including the following: a) analysis of endohedral fullerenes (Dorn); b) structure-function relationships of natural products exhibiting anticancer activity (Kingston); c) studies on rotaxanes and pseudorotaxanes (Gibson); d) studies on the structure, physical properties and reactivity of perfluoroarylated transition metal cyclopentadienyl complexes (Deck); e) investigations of catalysis using metal complexes of polysulfonated triarylphosphines in aqueous and biphasic solvents (Hanson); and f) studies on charge-transfer molecular magnets (Yee).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, including the preparation of more efficient catalysts; materials chemistry; pharmaceutical chemistry; and biochemistry.

在化学研究仪器和设施（CRIF）计划的支持下，弗吉尼亚理工学院和州立大学的化学系将使用用于小分子衍射法的CCD检测器获得X射线衍射仪。该设备将在许多领域的研究中增强以下各个领域的研究：a）分析富勒烯（DORN）； b）天然产物表现出抗癌活性的结构功能关系（金斯敦）； c）关于轮济和伪ta虫的研究（Gibson）； d）对全氟碳化过渡金属环戊二烯基络合物（甲板）的结构，物理特性和反应性的研究； e）使用水性和双相溶剂中的多硫化三磷酸的金属复合物进行催化研究（Hanson）；和f）对电荷转移分子磁体（YEE）的研究。X射线衍射仪可以准确，精确地测量分子的整个三维结构，包括键距离和角度，并提供有关分子相对于邻近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，包括制备更有效的催化剂。材料化学；药物化学；和生物化学。
