The 1 H, 13 C{ 1 H}, and 31 P NMR spectral parameters of some pyrophosphates were determined in CDCl 3 . The most complicated 1 H spectrum can be solved fully only as (A 3 MN)R 6 XX′R 6 ′(MNA 3 )′, where R 6 (= ―N(CH 3 ) 2 ) is coupled only to phosphorus (X). Second‐order coupling between phosphorus was found and solved with iterative analysis. A signal shape of one of the carbon resonance cannot be explained only with couplings. Explanation for exceptional shape was searched from molecular modeling results. Copyright © 2017 John Wiley & Sons, Ltd.
