摘要：

13C chemical shifts and 31P,13C coupling constants are reported for nine 1‐hydroxyalkylphosphonic and two additional phosphonic acids. The α‐substituent‐induced chemical shifts (α‐SCS) of the phosphonate group were calculated and their non‐additivity was observed. Good linear correlations exist between the chemical shifts and also between the α‐SCS parameters of 1‐hydroxyalkylphosphonic acids and the respective values of analogously constituted 1‐aminoalkylphosphonic acids.
