摘要：

The deuterium isotope effects on C-13 chemical shift of Schiff bases lithium salts, derivatives of amino acids (glycine, L-alanine, L-phenylalanine, L-valine, L-leucine, L-isoleucine and L-methionine) and 2-hydroxynaphthaldehyde in D2O as well as UV-vis spectra in different solvents have been measured. The results have shown that the lithium salts of the Schiff bases exist in the proton transferred NH form with intramolecular hydrogen bond in water. (c) 2005 Elsevier B.V. All rights reserved.
