摘要
设计和研制了一台用于检测固体中NMR宽谱线、型号为HC-4的CW-NMR波谱仪.谱仪由APPLE-Ⅱ微型计算机控制扫描、信号累加和数据处理.配备了自制的交叉线圈型和魔T型NMR探头和高温(1300K)探头,使谱仪具有较高的检测灵敏度和较强的测量功能,适用于检测固体中多种非质子核的NMR宽谱线及动态NMR测量.本文简要介绍该谱仪的基本结构、系统各部分的技术性能和测量应用的具体实例.
An 《HC-4》CW-NMR spectrometerr for the measurement of the multi- nuclei broad -line in the solid state was designed and manufactured. The scanning and accumulation of the spectra is controlled by the Apple-Ⅱ microcomputer. The home-made cross -coil probe and magic- tec probe together with the high-temperature device is equipped, and then it enables the spectrometer to held excellent sensitivity and wide applicatioa The spectraometer is appropriate to measure non - proton NMR spectra in solid state and dynamic NMR spectra . The whole construction and performance of spectrometer are described in this paper . The sectional specification and some test results aer also given .
