Purchase of Single-Crystal X-ray Diffractometer

这份来自化学研究仪器项目的合同将帮助布兰迪斯大学化学系购买x射线衍射仪和相关的数据分析系统。这种新仪器将极大地加强在许多领域的研究，包括：1)金属配合物的固态反应；2)立体负担配体；3)模型多肽中I型和II型b旋的构象分析；4)离子对结构；5)有机金属化学在材料科学和有机合成中的应用。从分子线到对映选择性试剂；6)全合成新方法的发展及其应用。x射线衍射仪用于对分子的完整三维结构进行精确的测量。得到的信息给出了给定分子的所有键距和键角的精确值，并给出了该分子相对于邻近分子的空间排列的准确信息。

This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at Brandeis University in the purchase of an x-ray diffractometer and an associated data analysis system. This new instrumentation will enhance greatly research in a number of areas including the following: 1) Solid state reactions of metal complexes, 2) Sterically encumbered ligands, 3) The conformational analysis of type I and type II B-turns in model polypeptides, 4) Ion pair structures, 5) Applications of organometallic chemistry to materials science and organic synthesis. From molecular wires to enantioselective reagents, 6) Development of new synthetic methods and their application of total synthesis. %%% 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 that molecule relative to the neighboring molecules.
