*** 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. ***

*** 9709977 SAMULSKI 该奖项由化学研究仪器和设施计划 (CRIF) 和多学科活动办公室 (OMA) 颁发，将帮助北卡罗来纳大学教堂山分校化学系购买一台配备 CCD 探测器的单晶 X 射线衍射仪。该设备将加强以下多个领域的研究：（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）簇链和混合价簇配合物的结构研究，（4）配位配体的对映选择性反应，（5）α、 金属发色团中的 β 和 γ 极化率，以及 (6) 13-15 (II-V) 单体、链、环和簇的结构研究。 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。 ***
