This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will assist the Department of Chemistry at The University of Texas in Austin to acquire an X-ray diffractometer with CCD detector. This equipment will enhance research in a number of areas including the following: (1) use of synthetic receptors and artificial enzymes; (2) construction of assemblies capable of selective and reversible binding of anions; (3) generation, structure and chemical properties of stable radicals; (4) long-range asymmetric induction to control stereochemistry over many achiral intervening atoms; (5) synthesis of complex products that have biological activity; and (6) synthesis of new porphyrin systems. 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.

该奖项由化学研究仪器和设施 (CRIF) 计划授予，将协助德克萨斯大学奥斯汀分校化学系购买一台带有 CCD 探测器的 X 射线衍射仪。 该设备将加强多个领域的研究，包括：（1）合成受体和人工酶的使用； (2)构建能够选择性且可逆地结合阴离子的组件； (3)稳定自由基的产生、结构和化学性质； （4）长程不对称诱导来控制许多非手性介入原子的立体化学； (5)具有生物活性的复杂产物的合成； (6)新卟啉系统的合成。 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。
