Nuclear Magnetic Resonance (NMR) spectroscopy is the most important 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. The Department of Chemistry at the University of Southern California will use this award from the Chemical Instrumentation Program to help acquire a high-field NMR spectrometer. Included among the areas of chemical research that will be enhanced by the acquisition are the following: 1) Synthetic coordination chemistry 2) Deuterium isotope effects on carbon-13 chemical shifts 3) Structural and spectroscopic studies on intramolecular donor-acceptor system 4) Proton and carbon-13 NMR of unsaturated silyl substituted polymers 5) Reactions of organometallic complexes.

核磁共振 (NMR) 光谱是化学家阐明分子结构的最重要工具。 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。 获得现代核磁共振波谱对于进行前沿研究的化学家来说至关重要。 南加州大学化学系将利用化学仪器项目的​​这一奖项来帮助购买高场核磁共振波谱仪。 此次收购将增强的化学研究领域包括：1) 合成配位化学 2) 氘同位素对碳 13 化学位移的影响 3) 分子内供体-受体系统的结构和光谱研究 4) 不饱和甲硅烷基取代聚合物的质子和碳 13 NMR 5) 有机金属配合物的反应。
