The surface-enhanced Raman (SER) scattering of p-nitroaniline adsorbed on silver colloids was investigated and compared with previous results obtained on a silver electrode. The SER spectra change signiΓcantly on varying the pH of the colloidal dispersions and correspond to di β erent adsorbed specie
Surface-enhanced Raman scattering (SERS) of hypoxanthine (HX) molecule on silver colloid confirms that the molecule in the surface adsorbed state exists as [keto-N9 H9] form at acidic and normal pH but as [enol-O6 H1, N9 H9] form at alkaline pH. It is substantiated by the appearance of an intense ca
