【 摘 要 】

A study of the effects of the interactions with amino acids on the vibrational spectra of Keggin heteropolyanions (Na_nH_3-n[XM₁₂O₄₀]^n-; n = 0,1,2,3; X = P^V, Si^IV, M = W^VI, Mo^VI) has been performed. Interactions occurred for all of the studied compounds leading to changes and splits in the stretching frequencies. Depending on the amino acid type, the IR bands for interbridge stretchings (M-O_b-M) and terminal stretchings (M-O_d) were affected.
