This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at the University of California, Irvine in the purchase of an x-ray diffractometer with a rotating anode x-ray source, associated data collection and analysis system and an upgrade of an older x-ray diffractometer. This new instrumentation will enhance greatly research in a number of areas including the following: 1) Synthesis and study of ligand-bridged transition metal compounds, 2) The chemistry of low-valent organosamarium (II) complexes, 3) Synthesis and chemistry of httrium and lanthanide metal complexes, 4) Silsesquioxanes as models for aluminosilicates, 5) Chemistry of organosulfur compounds, 6) Catalytic asymmetric synthesis of quaternary carbon centers, 7) Synthesis of complex polycyclics by palladium catalyzed polyene cyclizations, 8) Structural studies of bridgehead alkenes, 9) Molecular deformations and chemical reactivity. The rotating anode capability will permit structural studies which are not possible with stationary source radiation. %%% 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.

化学研究工具计划的该奖项将协助加利福尼亚大学欧文分校的化学系购买，以旋转阳极X射线源，关联的数据收集和分析系统以及升级较旧的X射线衍射仪。 这种新仪器将在许多领域进行大量研究，包括以下各个领域：1）配体桥梁过渡金属化合物的合成和研究，2）低价孔氨基膜（II）配合物的化学，3）合成和化学的化学4）4）硅胶硅酸盐的模型，5）有机硫酸盐化合物的化学，6）6）催化性不对称合成Quaternary Carbon中心，7）钯催化多元素环境研究的复杂多层次的复杂多环类化合物的结构，8）结构，8） 9）分子变形和化学反应性。 旋转的阳极能力将允许固定源辐射无法进行结构研究。 %% X射线衍射仪用于对分子的完整三维结构进行准确而精确的测量。 获得的信息给出了给定分子的所有键距离和键角的精确值，并提供了有关该分子相对于邻近分子的空间排列的准确信息。
