摘要：
A theoretical description of heteronuclear decoupling in solids, which takes into account homonuclear dipole-dipole interactions and spinning of the sample, is presented. Based on this analysis, a simple and efficient decoupling sequence nPPM is introduced. It consists of n/4 TPPM subcycles, followed by another n/4 subcycles with reversed phases.
