Abstrakt:	¹³ C chemical shifts and ³¹ P, ¹³ C coupling constants are reported for 20 amino-alkylphosphonic acids and two phosphonic acids. The substituent-induced chemical shifts of the phosphonate group were calculated and their non-additivity in 1-aminoalkylphosphonic acids was observed. Two stable conformers of 4-aminobutylphosphonic acid were detected by ¹³ C NMR. (Copyright © 1989 John Wiley & Sons, Ltd.)
