An FT NMR System for Undergraduate Instruction

一个200 MHz FT核磁共振光谱仪/系统正在我们的基础有机化学本科实验室中使用，我们在那里教授大量的理工科学生。同时，在结构解析、有机无机合成、物理化学和本科研究等较高级的实验课程中，该仪器也被学生（主要是专业学生）大量使用。一种仪器可以满足这些课程中学生的不同需求，因为现代FT核磁共振光谱仪非常灵活。它们可以被编程，以允许获得许多“常规”光谱所需的快速周转，同时保留更高级工作所需的全方位实验所需的所有潜力。在基础（“大二”）有机实验室中，我们能够给学生机会将NMR应用到他们自己的实验室工作中，这些工作越来越多地涉及到“调查”方法。在一台仪器上处理大量学生的后勤工作并不是微不足道的。在高级课程中，我们处理的数字较少，学生有足够的仪器时间，包括“下班时间”，不仅可以获得高分辨率光谱，还可以做许多其他复杂的实验，包括双共振解耦，l3C-off共振，NOE, 2D-NMR，变温和弛豫现象等。此外，我们为学生提供我们自己的光谱库，记录在“他们的”仪器上，用于讲座和相关研究。这台仪器对许多学生的教育产生了重大影响——每年有几百名学生——通过让他们接触到现代FT核磁共振系统。

9452527 Moore A 200 MHz FT NMR spectrometer/system is being used in our undergraduate laboratories in basic organic chemistry, where we teach large numbers of science and engineering students. At the same time, this instrument is being heavily utilized by students (mostly majors) in more advanced laboratory courses in structure elucidation, organic and inorganic synthesis, physical chemistry and undergraduate research. One instrument is meeting the differing needs of students in these courses because modern FT NMR spectrometers are so flexible. They can be programmed to permit the fast turnover needed to obtain many "routine" spectra while retaining all of the potential needed for the full range of experiments needed in more advanced work. In the basic ("sophomore") organic laboratory, we are able to give students the opportunity to apply NMR to their own laboratory work, which increasingly involves an "investigative" approach. The logistics of handling large numbers of students on one instrument are not trivial. In the advanced courses, where we deal with smaller numbers, students have adequate instrument time, including "off-hours", not only to obtain high-resolution spectra, but also to do many other sophisticated experiments, including double resonance decoupling, l3C-off resonance, NOE, 2D-NMR, variable temperature and relaxation phenomena, etc. In addition, we provide students with our own library of spectra, recorded on "their" instrument, to be used in lectures and associated study. This instrument is having a major impact on the education of many students - several hundred per year - by giving them access to a modern FT NMR system.
