Abstract The variations with pD of 31P, 13C and 1H n.m.r. chemical shifts for DO solution of MePOH and NH(CH)POH (n = 1, 2, 3) have been studied. In the aminoalkylphosphonic acids, δP is profoundly affected by amine deprotonation. ‘Cyclic’ conformations in which the amine group is close to the phosphonate group are proposed, with the strength of the amine-phosphonate interaction decreasing as n increases.
