摘要：

Ionization constants of N‐phosphonomethylglycine (glyphosate) and three structurally related plant‐growth regulators were determined by potentiometric titration. The effect of pD on the chemical shifts of the 1H and 13C nuclei of the methylene groups and of the 31P nucleus in these substrates was measured by NMR spectroscopy. The results allowed an assignment to be made of a specific site (carboxylic, phosphonic, ammonium) in the molecule to each of the determined pKa values. Copyright © 1990 John Wiley & Sons Ltd.
