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.

小行星9452527摩尔 200 MHz FT NMR光谱仪/系统正在我们的本科实验室基础有机化学中使用，在那里我们教大量的科学和工程专业的学生。 与此同时，这种仪器被学生（主要是专业）大量使用，在结构解析，有机和无机合成，物理化学和本科研究的更先进的实验室课程。 其中一种仪器可以满足这些课程学生的不同需求，因为现代FT NMR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范围实验所需的所有潜力。 在基础（“大二”）有机实验室，我们能够给学生的机会，应用核磁共振到自己的实验室工作，这越来越涉及到一个“调查”的方法。 在一台仪器上处理大量学生的后勤工作并不简单。 在高级课程中，我们处理较小的数字，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的光谱，而且还可以做许多其他复杂的实验，包括双共振去耦，13 C-关闭共振，NOE，2D-NMR，变温和弛豫现象等。记录在“他们的”仪器上，用于讲座和相关研究。该仪器对许多学生的教育产生了重大影响-每年数百人-通过让他们获得现代FT NMR系统。
