Incorporating FTNMR Across the Two-Year College Chemistry Curriculum

化学（12）核磁共振（NMR）是确定分子结构、分析化学混合物和确定反应动力学的不可或缺的工具。通过将过时的Varian EM360连续波NMR光谱仪转换为现代多核傅里叶变换仪器（FTNMR），为学生提供在实验室中使用NMR的实践经验的努力得到了极大的帮助。这种具有成本效益、用户友好的解决方案可实现快速数据采集，使学生收集光谱成为常规程序。从化学教育杂志的实验和FTNMR纳入当前的实验改编允许学生在他们的化学教育的各个阶段都有机会获得该仪器。FTNMR在整个课程中用于展示入门化学中技术的力量，确定普通化学中的分子结构，并在有机化学中进行多核和二维实验。早期和持续接触FTNMR加强了重要的化学概念，吸引学生，帮助发展他们解决问题的能力，并使他们接触到化学技术的使用。

Chemistry (12) Nuclear magnetic resonance (NMR) is an indispensable tool for the determination of the structures of molecules, the analysis of chemical mixtures, and the determination of reaction kinetics. Efforts to provide students with hands-on experience using NMR in the laboratory are greatly aided by converting an outdated Varian EM360 continuous-wave NMR spectrometer into a modern multinuclear Fourier-transform instrument (FTNMR). This cost-effective, user-friendly solution allows rapid data acquisition, making student collection of spectra a routine procedure. Adaptation of experiments from the Journal of Chemical Education and incorporation of FTNMR into current experiments allow students at all stages of their chemical education to have access to the instrument. FTNMR is used across the curriculum to demonstrate the power of the technique in Introductory Chemistry, to determine molecular structure in General Chemistry, and to perform multinuclear and two- dimensional experiments in Organic Chemistry. Early and continued exposure to FTNMR reinforces important chemical concepts, engages students, helps develop their problem-solving skills, and exposes them to the uses of technology in chemistry.
