Acquisition of a High Field NMR Spectrometer

这项来自化学研究仪器项目的奖励将帮助三一大学化学系获得一台300兆赫的核磁共振光谱仪，用于以下化学领域的研究调查：(1)由手性dirhodium(II) carboxamides催化的高度对映选择性转化；(2)抗芳构性和高价性；(3)位导向光化学：受电子和应变效应干扰的蒽衍生物的环加成。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。从这些核磁共振研究的结果是有用的领域，如聚合物和催化，并在生物学。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Trinity University acquire a 300 MHz NMR spectrometer which will be used in research investigations in the following areas of chemistry: (1) highly enantioselective transformations catalyzed by chiral dirhodium(II) carboxamides; (2) anti-aromaticity and hypervalency in hydrocarbon dications; and (3) site directed photochemistry: cycloadditions to anthracene derivatives perturbed by electronic and strain effects. 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 and catalysis, and in biology.
