With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at The University of Southern California will acquire a 400 MHz Fourier Transform NMR Spectrometer. This equipment will enable researchers to carry out research on the following: 1) activation and functionalization of alkanes; 2) development of new molecules and polymers for optical and photonic applications; 3) bio-organic probes and bio-active organophosphorus compounds; 4) selective functionalization of hydrocarbon CH bonds catalyzed by homogeneous metal complexes; 5) new synthetic methods and synthesis of bioactive molecules; and 6) studies of carbocations and related chemistry. 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, to 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 spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic chemistry, biochemistry and materials chemistry.

凭借化学研究仪器和设施（CRIF）计划的这一奖项，南加州大学化学系将获得400 MHz傅里叶变换NMR光谱仪。该设备将使研究人员能够开展以下研究：1）烷烃的活化和功能化; 2）用于光学和光子应用的新分子和聚合物的开发; 3）生物有机探针和生物活性有机磷化合物; 4）均相金属配合物催化的烃CH键的选择性功能化; 5）新的合成方法和生物活性分子的合成; 6）碳正离子及相关化学研究。 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光谱仪是必不可少的。这些NMR研究的结果将对合成有机化学、生物化学和材料化学产生影响。
