摘要：

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 thal scales chemical shifts to zero, thereby removing the barrier to spin exchange among interacting nuclei. Transfer of spin coherence is achieved by a transverse mixing sequence in which eight pi-pulses, pi(x)-pi(x)-pi(y)-pi(y)-pi(-y)-pi(-y)pi(-x)-pi(-x), are applied per rotor period. Spectra of triply-labeled 1,2,3-C-13(3)-D,L-alanine are presented, which demonstrate correlations among all three carbon spins.
