Through this project, the Chemistry Department is upgrading a 21- year-old 30-Mhz NMR spectrometer, which had been inoperable, with state-of-the-art 200-MHz FT-NMR capabilities. This new instrument provides the ability to perform significant undergraduate research projects, while being simple enough to allow upper-division (e.g., sophomore-level and up) students to record their own spectra routinely for instructional laboratories. The exposure of students to this instrument begins in Organic Chemistry, the normal sophomore-level course, where they record the spectra for the products synthesized during the first-semester lab course. During the second-semester lab, open-ended project-based experiments are performed. Without a functional NMR spectrometer, the incorporation of this type of experiment is extremely difficult. The upper-division courses all, with the current exception of Physical Chemistry, incorporate advanced NMR techniques in their laboratory offerings. The most notable is the ability to offer a meaningful lab component to a newly introduced Spectroscopy class. Undergraduate research is enjoying an immediate elevation in opportunities with the presence of an FT NMR spectrometer. Two of the faculty on staff are increasing their activity in research as a result of increased demand. Their projects require NMR capabilities, ranging from routine 1H to 31P. The spectrometer meets both the current requirements, as well as the foreseeable future needs.

通过这个项目，化学系正在升级一个有21年历史的30兆赫核磁共振光谱仪，这是无法操作的，具有最先进的200兆赫FT-NMR能力。 这种新的仪器提供了执行重要的本科研究项目的能力，同时足够简单，允许上级部门（例如，本科及以上）的学生记录自己的光谱教学实验室例行。 学生接触这种仪器开始于有机化学，这是一门普通的化学水平课程，他们在第一学期的实验室课程中记录合成产物的光谱。 在第二学期的实验室，开放式的基于项目的实验进行。 如果没有一个功能NMR光谱仪，这种类型的实验是非常困难的。 所有的高年级课程，与物理化学目前的例外，将先进的NMR技术在他们的实验室产品。 最值得注意的是能够为新引入的光谱学课程提供有意义的实验室组件。 随着FT NMR光谱仪的出现，本科生的研究机会立即增加。 由于需求增加，两名教职员工正在增加他们的研究活动。 他们的项目需要NMR能力，从常规的1H到31 P。 光谱仪既满足当前的要求，也满足可预见的未来需求。
