Purchase of a Nuclear Magnetic Resonance Spectrometer

这份来自化学研究仪器和设施项目的合同将帮助威奇托州立大学化学系获得一台300 MHz核磁共振光谱仪。这种设备将加强若干领域的研究，包括：(1) metacycyclophes的合成与表征，(2)基于分子识别方法的新型卟啉化学传感器和供体-受体系统的研究，(3)腈取代三吡唑硼酸盐-分子材料的金属配合物，(4)丝氨酸蛋白酶的机制抑制剂，(5)太阳能转化分子，(6)基团转移聚合形成胶束，水溶性二嵌段共聚物，(7)l-抗坏血酸的化学性质。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 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.
