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.

化学研究仪器和设施计划的这一奖项将帮助威奇托州立大学化学系获得300 MHz NMR光谱仪。 该设备将加强多个领域的研究，包括以下领域：（1）间环芳的合成和表征，（2）利用分子识别方法研究新型卟啉基化学传感器和供体-受体系统，（3）腈取代三吡唑硼酸盐的金属配合物-分子材料，（4）基于机理的丝氨酸蛋白酶抑制剂，（5）用于太阳能转换的分子，（6）通过基团转移聚合形成胶束的水溶性二嵌段共聚物，和（7）L-抗坏血酸的化学。 核磁共振（NMR）光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。对于从事前沿研究的化学家来说，使用最先进的NMR光谱分析技术是必不可少的。这些NMR研究的结果在聚合物、催化和生物学等领域都很有用。
