Cu colloid was prepared by oxidation-reduction; it was relatively steady in fixed conditions, with size about 10-30 nm. The Raman spectrum of p-hydroxybenzoic acid (PHBA) in Cu colloid solution with the ultraviolet (UV) excitation at 325 nm, was obtained, even it is usually difficult to obtain Raman signals in Ag or An in the UV region. It was found that the Raman signal intensities result from the resonance enhanced of surface plasmon resonance of Cu nanoparticles excited at 325 nm. The adsorption behavior of PHBA on the Cu nanoparticles was studied by combining with density functional theory (DFT); it was found that the calculated Raman frequencies were in good agreement with experimental value. So one can conclude that the simplified model is probably reasonable to describe some resonance Raman experiments. (c) 2006 Elsevier B.V. All rights reserved.
