本文描述了一种以单板机为基础的多脉冲序列可编程辅助控制器(PCMP),在常规液体NMR谱仪上实现多脉冲实验。应用PCMP获得了固体的J—耦合化学位移各向同性谱、化学位移缩窄谱,同时也可以完成时间平均旋进频率交叉极化实验以及组合脉冲宽带去耦实验,进一步开拓了常规液体谱仪的功能。
This paper describes a single-board multi-pulse sequence programmable auxiliary controller (PCMP) based on the conventional liquid NMR spectrometer to achieve multi-pulse experiments. The solid-state J-coupled chemical shift isotropy spectrum and chemical shift narrowing spectrum were obtained by using PCMP. At the same time, time-averaged precession frequency cross-polarization experiment and combined pulse broadband decoupling experiment were completed, which further opened up the conventional liquid spectrometer Function
