A simple phase alternated multiple pulse sequence is described which enables the chemicai shift between two inequivalent sites in a solid to be resolved. Preliminary experiments on solid zinc phosphide give a shift between the two inequivalent sites of 34 ppm. which could include a mean anisotropic
High-resolution 13C NMR spectra of 15 samples of uncomplexed and metalcomplexed tetranactin and nonactin were recorded in the solid state, revealing characteristic displacements of peaks due to complex formation and the effect of crystalline packing on the 13C chemical shifts and spidattice relaxati
