Abstract

Heteronuclear spin interactions in solids and anisotropic liquids can be removed by phase modulated decoupling sequences with frequency sweep, such as -TPPM and its variants. The performance of these sequences in isotropic spin systems with regard to the experimental parameters, phase angle, and decoupler offset is presented here. A comparison is made with other commonly used heteronuclear decoupling schemes in liquids, namely, WALTZ-16, GARP, and MLEV. Also, the trajectories of nuclear magnetization vector of abundant nuclei in a simple spin system during TPPM and -TPPM decoupling sequences are traced out using computer simulations.

基于双脉冲相位调制的解耦方案消除各向同性系统核磁共振波谱中的异核自旋相互作用:实验和数值模拟分析
固体和各向异性液体中的异核自旋相互作用可以通过带频率扫描的相位调制解耦序列去除,例如-TPPM及其变体。本文给出了这些序列在各向同性自旋系统中与实验参数、相位角和解耦偏移有关的性能。并与其他常用的液体异核解耦方案,即华尔兹-16、GARP和MLEV进行了比较。此外,利用计算机模拟,我们还得到了简单自旋系统中富核在TPPM和-TPPM解耦过程中的核磁化矢量轨迹。
