Abstract

The ^1^H and ^31^P NMR spectra of 3‐amino‐3‐phosphonatopropionic acid, a phosphonic derivative of aspartic acid, have been measured and completely analysed for 14 pH values. The vicinal coupling constants, ^3^J(HH) and ^3^J(HP), were used to obtain information on the rotational isomerism of the amino acid. The most stable conformer is the one where the phosphonic and β‐carboxyl groups are in trans position to each other.

The long-standing issue of the conformational change of myo-inositol hexakisphosphoric acid (H 12 inhp), commonly called phytic acid, was resolved by low-temperature pH\* studies and NMR spectroscopy. Lowtemperature experiments on phytic acid, in a suitable mixed solvent and in the appropriate pH\*
