Purchase of Replacement Instrument for the Gemini-300 NMR Spectrometer

这份来自化学研究仪器和设施（CRIF）项目的合同将帮助华盛顿大学化学系购买一台300兆赫的核磁共振（NMR）光谱仪。这种设备将加强若干领域的研究，例如：(1)复杂有机分子的合成，(2)利用组合技术开发过渡金属催化不对称反应的新配体，(3)有机金属溶液-液-固生长三元III-V半导体纳米晶须，(4)硅烯的分子设计，(5)纯位点特异性光产物DNA的鉴定和制备，以及(6)合成聚合物化学。核磁共振（NMR）波谱是化学家用来阐明分子结构的最有力的工具。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液中分子之间相互作用的动力学。获得最先进的核磁共振光谱是必不可少的化学家谁正在进行前沿研究。这些核磁共振研究的结果在聚合物、催化和生物学等领域是有用的。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will assist the Department of Chemistry at Washington University to purchase a 300 MHz nuclear magnetic resonance (NMR) spectrometer. This equipment will enhance research in a number of areas such as the following: (1) the synthesis of complex organic molecules, (2) the use of combinatorial technology in the development of new ligands for transition metal catalyzed asymmetric reactions, (3) organometallic solution-liquid -solid growth of ternary III-V semiconductor nanowhiskers, (4) the molecular design of silylenes, (5) the identification and preparation of pure site-specific photoproduct-containing DNA, and (6) synthetic polymer chemistry. Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution. Access to state-of-the-art NMR spectrometry is essential to chemists who are carrying out frontier research. The results from these NMR studies are useful in the areas such as polymers, catalysis, and in biology.
