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.

该奖项由化学研究仪器和设施 （CRIF）计划将协助华盛顿化学系 大学购买300 MHz核磁共振仪（NMR） 光谱仪 这一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)组合技术在新配体开发中的应用 对于过渡金属催化的不对称反应，（3）有机金属 三元III-V族半导体的溶液-液-固生长 纳米晶须，（4）亚甲硅烷基的分子设计，（5） 纯定点鉴定和制备 含光产物的DNA，和（6）合成聚合物化学。 核磁共振（NMR）光谱是最强大的工具， 化学家用来阐明分子结构的仪器。 它用于识别未知物质，表征特定物质， 分子内原子的排列，并研究 溶液中分子间的相互作用获得最新技术 核磁共振谱是化学家进行前沿研究的基础 research.这些NMR研究的结果在以下领域是有用的， 如聚合物、催化剂和生物学。
