Nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique in the organic chemistry laboratory for elucidation of molecular structure. Miniaturization of NMR technology has attracted attention and acceptance due to a considerable reduction in the cost to acquire and maintain the instrument. The advent of low-field, low-cost, and low-maintenance tabletop NMR technology has provided academic institutions with limited resources the option of hands-on NMR experimentation for undergraduates. The application of the tabletop NMR instrument in the organic chemistry laboratory to analyze an unknown liquid, which can be an ester, an aldehyde, an alcohol, or a ketone, together with infrared (IR) spectroscopy and classic chemical color tests, is herein described.

将台式NMR光谱仪并入有机化学实验室：未知液体的分析

核磁共振（NMR）光谱是有机化学实验室中阐明分子结构必不可少的技术。由于大大降低了购置和维护该仪器的成本，NMR技术的小型化已引起关注和接受。低场，低成本和低维护的台式NMR技术的出现为资源有限的学术机构提供了针对大学生的动手NMR实验的选择。本文介绍了台式NMR仪器在有机化学实验室中的应用，以分析未知液体（可以是酯，醛，醇或酮），并结合红外（IR）光谱和经典的化学颜色测试。 。
