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 Efforts to provide students with hands-on experience using NMR in the laboratory are greatly aided by converting an outdated Varian EM360 continuous-wave NMR spectrometer into a modern multinuclear Fourier-transform instrument (FTNMR).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.

核磁共振是测定分子结构、分析化学混合物和测定反应动力学不可缺少的工具。通过将过时的瓦里安EM360连续波核磁共振波谱仪改装成现代多核傅立叶变换仪(FT核磁共振)，为学生提供在实验室使用核磁共振的实践体验的努力得到了极大的帮助。这一经济高效、用户友好的解决方案允许快速获取数据，使学生收集光谱成为例行公事。改编自《化学教育杂志》的实验，并将FT核磁共振纳入目前的实验，使处于化学教育所有阶段的学生都可以使用该仪器。傅立叶变换核磁共振在整个课程中被用来展示该技术在入门化学中的力量，在普通化学中确定分子结构，并在有机化学中进行多核和二维实验。早期和持续地接触FT核磁共振强化了重要的化学概念，吸引了学生，帮助他们发展解决问题的技能，并使他们接触到技术在化学中的应用。
