Early e β orts to utilize 15N NMR spectroscopy in structure elucidation studies were often frustrated by the low gyromagnetic ratio and the low natural abundance (0.37%) of the nuclide. The advent of 1H and (c N ) inverse-detected 2D NMR methods has eliminated many of the difficulties inherent to the
## Abstract The naturalβabundance ^15^Nβnuclear magnetic resonance (nmr) spectrum of the cyclic decapeptide gramicidin S has been measured and assigned in the solvents dimethyl sulfoxide, methanol, and 2,2,2βtrifluoroethanol. Three methods have been investigated to distinguish between peptide group
