Abstract

A spin-lock pulse sequence has been used in solid-state1H NMR to suppress the dominant water signal and to observe, under magic-angle spinning, very narrow signals of di-n-propylamine template in the hydrated molecular sieve VPI-5. Results suggest that the technique can be extended to the study of other molecular sieves.

水合磷酸铝-5中有机模板的高分辨率固态1h核磁共振谱
采用自旋锁脉冲序列在固态1h NMR中抑制了主导水信号,并观察到水合分子筛VPI-5中在魔角旋转下二正丙胺模板的极窄信号。结果表明,该技术可以推广到其他分子筛的研究中。
