摘要:
One‐dimensional selective scalar transfer experiments are presented for the analysis of 13C NMR data for multilabelled molecules. ‘Classical’ 13C COSY experiments rapidly show limitations when a complete determination of remote coupling constants is required. Conversely, combination of 1D COSY and RELAY affords all the required information very rapidly and accurately. Three 13C‐labelled monosaccharides exhibiting different degrees of spectral complexity are used to illustrate the merits of these techniques. Copyright © 1990 John Wiley & Sons, Ltd.
