With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Kansas 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) structural elucidation of anion coordination chemistry; b) elucidation of the effects of non-covalent interactions on metal ion reactivity; c) probing structure-function ramifications of tetrazamacrocyclic metal complexes in catalytic oxidation reduction reactions; d) examination of the influence of peptide porphyrin interactions on helix stability and on electron transfer; ;e) elucidation of structural influences on asymmetric metathesis catalysts; and f) studies of the growth mechanism for mercury-based high temperature superconductors.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, chemical sensors, high temperature superconductors; and biochemistry.

在重大研究仪器（MRI）计划的支持下，堪萨斯大学化学系将获得一台带有CCD检测器的X射线衍射仪，用于小分子衍射。这一设备将加强若干领域的研究，包括：a）阴离子配位化学的结构说明; B）非共价相互作用对金属离子反应性的影响说明; c）探测四氮杂大环金属络合物在催化氧化还原反应中的结构-功能衍生物; d）检验肽卟啉相互作用对螺旋稳定性和电子转移的影响;;e）阐明结构对不对称复分解催化剂的影响;以及f）研究汞基高温超导体的生长机制。X射线衍射仪可以精确测量分子的完整三维结构，包括键距和键角，并提供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，包括制备更有效的催化剂、化学传感器、高温超导体和生物化学。
