- 中文摘要: Two-dimensional NMR spectra of gramicidin S have been measured. With the combination of COSY (through bond interaction) and NOESY (through space interaction) spectra, it is possible to identify amino acid residues sequentially. It is found that the phase-sensitive 2D technique is superior to the absolute value mode. A double quantum filtering technique could be combined with phase-sensitive COSY experiments to obtain the optimum results.
