Upgrade of Departmental Electron Paramagnetic Resonance Facility

*9709977萨穆尔斯基该奖项来自化学研究仪器和设施计划和多学科活动办公室，将帮助北卡罗来纳大学教堂山分校化学系获得配备ccd探测器的单晶x射线衍射仪。该设备将加强以下领域的研究：(1)烯烃聚合反应中催化中间体的结构，(2)自由基加成反应中立体化学的控制，(3)簇链和混价簇合物的结构研究，(4)配位配体的对映选择性反应，(5)金属生色团中α，β和伽马极化率之间相互关系的基础研究，以及(6)13-15(II-V)单体、链、环和簇合物的结构研究。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。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。***

*** 9709977 SAMULSKI This award from the Chemistry Research Instrumentation and Facilities Program (CRIF) and the Office of Multidisciplinary Activities (OMA) will help the Department of Chemistry at University of North Carolina at Chapel Hill acquire a single crystal x-ray diffractometer equipped with a CCD detector. The equipment will enhance research in a number of areas including the following: (1) structures of catalytic intermediates in olefin polymerization reactions, (2) control of stereochemistry in radical addition reactions, (3) structural studies of cluster chains and mixed-valance cluster complexes, (4) enantioselective reactions of coordinated ligands, (5) a fundamental study of the interrelationships between alpha, beta, and gamma polarizabilities in metal chromophores, and (6) structural studies of 13-15 (II-V) monomers, chains, cycles and clusters. 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 neighboring molecules. ***
