Chemistry (12)Nuclear magnetic resonance (NMR) spectroscopy has attained a preeminent position as a tool for use in chemistry and related fields, such as biochemistry, molecular biology, pharmaceutics, and medicinal chemistry. The closely related discipline of Magnetic Resonance Imaging (MRI) extends the reach of this technology into such fields as clinical medicine and material science. Thus, it is important that undergraduate students entering any of these fields be given a clear understanding of the principles basic to NMR. It is doubly important that students who go on to teach physical science at the secondary or post-secondary level should have a firm grounding in this technology. However, meeting this need for a class of several hundred sophomore organic chemistry students is a daunting task, Nevertheless, our Chemistry Department is supporting an initiative to expose all students taking chemistry to sophisticated equipment of the types they are likely to encounter in their future careers. An NMR spectrometer consisting of an existing 9.4 Tesla magnet, a new 400 MHz console, sample handling robot, pulsed-field-gradient system, pulsed-field-gradient probe, and shim system is serving as the basis for this initiative. The host workstation of this spectrometer is connected to the LAN via ethernet. Given this level of automation, a throughput of hundreds of samples per week is entirely realistic. The step that is not being rushed is the interaction of the student with the data. Each student spends as much time as desired processing, examining, and incorporating the data into laboratory reports. Appropriate NMR experiments are being modified from those available in the literature and are being integrated into the large sophomore organic chemistry course, further extending the model at Florida State University for using an NMR in large classes. In addition, the NMR is being used in the qualitative organic chemistry, advanced analytical chemistry, advanced physical chemistry, and biochemistry courses, and by students involved in undergraduate research.

化学（12）核磁共振（NMR）光谱学作为化学和相关领域的工具，如生物化学，分子生物学，制药学和药物化学，已经取得了卓越的地位。与磁共振成像（MRI）密切相关的学科将这项技术的范围扩展到临床医学和材料科学等领域。因此，重要的是，进入任何这些领域的本科生被给予NMR基本原理的清晰理解。在中学或中学后阶段继续教授物理科学的学生应该在这项技术方面有坚实的基础，这一点尤为重要。然而，满足这一需求的一类几百大二有机化学学生是一项艰巨的任务，然而，我们的化学系正在支持一项倡议，让所有学生采取化学的类型，他们可能会遇到在他们未来的职业生涯中的复杂设备。由现有的9.4特斯拉磁体、新的400 MHz控制台、样品处理机器人、脉冲场梯度系统、脉冲场梯度探头和匀场系统组成的NMR光谱仪是这一举措的基础。主机工作站通过以太网与局域网相连。考虑到这种自动化水平，每周数百个样本的吞吐量是完全现实的。学生与数据的互动是不急于采取的步骤。每个学生花尽可能多的时间来处理，检查，并将数据纳入实验室报告。适当的核磁共振实验正在修改，从那些在文献中，并被纳入大二有机化学课程，进一步扩展模型在佛罗里达州立大学使用NMR在大班。此外，NMR还被用于定性有机化学，高级分析化学，高级物理化学和生物化学课程，以及参与本科研究的学生。
