Purchase of a 300 MHz NMR Spectrometer (Chemistry)

核磁共振（NMR）光谱是化学家用来研究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。获得现代核磁共振光谱学对从事前沿研究的化学家来说是必不可少的。这份来自化学共享仪器项目的奖金将帮助佛罗里达大学化学系获得一台高场核磁共振光谱仪。此次收购将加强的化学研究领域包括：1)取代基在周环反应中的动力学和立体化学效应2)分子内烯反应和镧系元素介导的环化3)金属蛋白的研究衍生物与气相无机化学4)应变对过渡金属键合配体sigma和pi的化学影响5)昆虫和植物相关天然产物的结构解析和全合成及新的合成方法6)三叉齿；无环二烯聚合的多官能配体和催化剂。

Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool available to the chemist 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 modern NMR spectroscopy is essential to chemists who are carrying out frontier research. This award from the Chemistry Shared Instrumentation Program will help the Chemistry Department at the University of Florida to acquire a high-field NMR spectrometer. The areas of chemical research that will be enhanced by the acquisition include: 1) Kinetic and stereochemical effects of substituents in pericyclic reactions 2) Intramolecular ene reaction and lanthanide mediated cyclizations 3) Studies of metalloprotein derivatives and gas-phase inorganic chemistry 4) The effect of strain on the chemistry of ligands sigma and pi-bonded to transition metals 5) Structure elucidation and total synthesis of insect and plant related natural products and new synthetic methodology 6) Tridentate, polyfunctional ligands and catalysts for the polymerization of acyclic dienes.
