โœฆ Synopsis

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 interacting nuclei. Transfer of spin coherence is achieved by a transverse mixing sequence in which eight n pulses, rr,-rc,-rr,-rc,-n_,n_,-~_,-lr_, are applied per rotor period. Spectra of triply-labeled 1,2,3-13C3-D,Galanine are presented, which demonstrate correlations among all three carbon spins.

Recovery of the magnetic dipolar interaction between nuclei bearing the same gyromagnetic ratio in rotating solids can be promoted by synchronous rf irradiation. Determination of the dipolar interaction strength can serve as a tool for structural elucidation in polycrystalline powders. Spinning freq
