Abstract

Results are presented of research on the influence of Na, Mg, Cd, Al, La(III), Pb(II), Hg(I), and Hg(II) on the aromatic system of salicylic acid. Salicylic acid is regarded here as a model compound representing a wide group of aromatic ligands which are components of enzymes. The number, frequency, and relative intensities of bands in thé vibrational (Raman and IR) spectra and the frequencies of the π → π* bands in the electronic (UV) spectra were analyzed. The analysis showed that metal-aromatic ligand complex formation causes significant changes in the frequencies and relative intensities of the bands associated with the aromatic system in the following regions: 1640-1370, 1350-1300, 1200-1090, and 800-650 cm⁻¹. It was concluded that Na, Hg(I and II), Pb(II), and Cd perturb the aromatic system of salicylic acid, whereas La(III) and Al stabilize it.
