The objective of the project is to add pulsed nuclear magnetic resonance (NMR) experiments to the experimental physics course and to develop the experiments. Modular components used which are incorporated into a working NMR system with which students can learn to measure nuclear relaxation times, use Fourier transforms in NMR measurements, use quadrature detection techniques and use multiple pulse sequences to remove dipolar broadening in solid samples. Students who work with these experiments gain understanding of many aspects of physics involved in NMR, including slow molecular motions in solids, negative absolute temperature in discrete level spin systems, and many of the basic ideas upon which the very important and widely useful technique -- magnetic resonance imaging (MRI) -- has been developed. Resulting experiments will be shared through presentations or publications.

该项目的目标是在实验物理课程中增加脉冲核磁共振实验，并发展这些实验。使用的模块化组件被整合到一个有效的核磁共振系统中，学生可以在该系统中学习测量核磁共振测量中的核弛豫时间，使用傅立叶变换进行核磁共振测量，使用正交检测技术和使用多个脉冲序列来消除固体样品中的偶极展宽。从事这些实验的学生将了解核磁共振所涉及的物理学的许多方面，包括固体中的慢分子运动，离散水平自旋系统中的负绝对温度，以及许多非常重要和广泛有用的技术-磁共振成像(MRI)-的基本概念。实验结果将通过演示文稿或出版物分享。
