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
