✦ Synopsis

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 "C-labelled monosaccharides exhibiting different degrees of spec- tral complexity are used to illustrate the merits of these techniques. KEY WORDS 13C-13C coupling Selective excitation Gaussian pulse 13C enriched carbohydrate
