title: Vibrational study of the salicylate interaction with metallic ions and surfaces.
abstract: Infrared and Raman spectroscopy are used in this work to study the metallic complexes of salicylic acid with silver and copper, comparing the interaction between salicylate and the cations (Ag+ and Cu2+) in the metal complexes with the SERS spectra when adsorbed on colloidal metal surfaces of the same metals. The salicylate complexes with the above metals were compared to those of Na+, Fe3+ and Al3+ cations. A different interaction mechanism is deduced for salicylate in the metal complex and when adsorbed on the metal surface.
