Notes:
The results of the direct analysis of the ABX spin system present in two symmetrical diphosphonates containing a single vinylic 13C nucleus are presented. This allows a comparison to be made with the two-dimensional methods used by Beckmann et al. Significant differences are found in the results obtained: the need to recognize the existence of isotopic chemical shifts is emphasized.
