Abstract: ESR spectra of Gadolinium (Ⅲ) complexes with amino acids have not been reported up to now. Synthesis of five amino acid-Gd(Ⅲ) complexes is reported in this paper. The ESR spectra of their powder samples and that of Gd (Ⅲ) complexes in Y zeolite were determined at various temperatures. The crystal field, symmetry and the bonding character of these complexes are discussed.

Key words: Amino acid, Gadolinium (III) complexes, ESR spectra
