Rk. Harris et al., DIRECT ANALYSIS OF THE ABX SPIN SYSTEM IN 2 SYMMETRICAL DIPHOSPHONATES - COMPARISON WITH 2-DIMENSIONAL METHODS, Magnetic resonance in chemistry, 31(12), 1993, pp. 1085-1087
The results of the direct analysis of the ABX spin system present in t
wo symmetrical diphosphonates containing a single vinytic C-13 nucleus
are presented. This allows a comparison to be made with the two-dimen
sional methods used by Beckmann et al. Significant differences are fou
nd in the results obtained: the need to recognize the existence of iso
topic chemical shifts is emphasized.
