The pH dependence of spin‐spin coupling constants J P‐O‐P of ADP and ATP has been determined from the phosphorus NMR spectra at 0°. The variation curves have been interpreted as titration curves. These give different p K values. Comparison with the tripolyphosphate shows the existence of triphosphate chain structural deformation in the nucleotides.
