A two-dimensional homonuclear correlation experiment for magic angle spinning NMR spectroscopy of polycrystalline solids is described. The approach involves application of a multiple pulse mixing period that scales chemical shifts to zero, thereby removing the barrier to spin exchange among interact

β¦ Synopsis
Coherence transfer by an isotropic mixing process is used for two-dimensional heteronuclear shift correlation in magicanple-spin&q solid-state spectroscopy. Selective coherence transfer is conlbiied with efficient homonuclear and hereronuclear dipolar decoupling to obtain well-resolved shift corre!ntion spectra.
