MRI: Acquisition of Laboratory Instrumentation for Department of Natural Sciences

约翰逊史密斯大学化学系将获得一台90 MHz核磁共振（NMR）光谱仪和一台原子吸收光谱仪。该设备将使研究人员能够对环境中金属的命运和运输进行研究。这所大学的学生将积极参与研究项目，并在高级实验课程中使用这些仪器。原子吸收（AA）和核磁共振（NMR）光谱是非常强大的工具，是大多数现代分析化学实验室的支柱。核磁共振用于识别未知物质，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仪是必不可少的化学家谁正在进行前沿研究。AA光谱法可以明确地鉴定原子种类。这些研究的结果将对环境化学产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Johnson C. Smith University will acquire a 90 MHz nuclear magnetic resonance (NMR) spectrometer and an atomic absorption spectrometer. This equipment will enable researchers to carry out studies on the fate and transport of metals in the environment. Students at this primarily undergraduate institution will be active participants in the research projects and will also use these instruments in their advanced laboratory courses. Atomic absorption (AA) and nuclear magnetic resonance (NMR) spectroscopy are very powerful tools and are the mainstay of most modern analytical chemistry laboratories. NMR 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. AA spectroscopy allows for the unequivocal identification of atomic species. The results from these studies will have an impact in environmental chemistry.
