Purchase of a Nuclear Magnetic Resonance Spectrometer

这项来自化学研究仪器和设施计划的奖项将帮助威奇托州立大学化学系获得一台300 MHz的核磁共振光谱仪。该设备将加强以下领域的研究：(1)偏环膦化合物的合成和表征；(2)新型卟啉类化学传感器和供体-受体体系的分子识别研究；(3)氰基取代的三吡唑硼酸盐金属络合物--分子材料；(4)丝氨酸蛋白酶的机理抑制剂；(5)太阳能转换分子；(6)胶束形成的水溶性两嵌段共聚物；(7)L-抗坏血酸的化学。核磁共振波谱是化学家用来解释分子结构的最有力的工具。它被用来识别未知物质，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。对于正在进行前沿研究的化学家来说，获得最先进的核磁共振光谱是必不可少的。这些核磁共振研究的结果在聚合物、催化和生物学等领域都是有用的。

This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at Wichita State University to acquire a 300 MHz NMR Spectrometer. This equipment will enhance research in a number of areas including the following: (1) synthesis and characterization of metacyclophanes, (2) studies on novel porphyrin-based chemosensors and donor-acceptor systems using molecular recognition approach, (3) metal complexes of nitrile- substituted trispyrazolylborates-molecular materials, (4) mechanism-based inhibitors of serine proteinase, (5) molecules for solar energy conversion, (6) micelle-forming, water-soluble diblock copolymers by group transfer polymerization, and (7) chemistry of l-ascorbic acid. 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.
