This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at University of Wyoming to acquire an upgrade of a Siemens P3 X- ray diffractometer to the P4 model. This equipment will enhance research in a number of areas including the following: (1)structural investigations of fluoroalkylphosphine complexes, (2) structural and reactivity correlations in iron nitrosyls, (3) Diels-Alder reactions within vesicles and the aggregate morphology of novel surfactants, and (4) structural studies of nitrogen oxyanions and luminescent molecular rectangles. 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项目的这一奖项将帮助怀俄明大学化学系将西门子P3型X射线衍射仪升级到P4型。该设备将加强以下领域的研究：(1)氟烷基膦配合物的结构研究；(2)亚硝酸铁的结构和反应相关性；(3)囊泡内的Diels-Alder反应和新型表面活性剂的聚集形态；以及(4)含氮氧阴离子和发光分子矩形的结构研究。X射线衍射仪被用来对分子的全部三维结构进行精确和精确的测量。得到的信息给出了给定分子的所有键距和键角的精确值，并提供了关于该分子相对于邻近分子的空间排列的准确信息。
