Abstract

The results of the direct analysis of the ABX spin system present in two symmetrical diphosphonates containing a single vinylic ^13^C 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.

Two different capillary electrophoretic separation modes for the analysis of UDP-sugars have been tested. In comparison to the traditionally used HPLC method the micellar electrokinetic capillary chromatography (MECC) as well as the capillary zone electrophoresis (CZE) results in an improvement of t
