A new method for the preparation of SERS active Cu electrode surfaces with high enhancement factors, which enable the observation of high quality spectra in the low-frequency region at different chloride concentrations, is proposed. Low-frequency modes at 160 and 145 cm-t are attributed to Cu-Cu vib
Enhanced Raman scattering has been observed from the hexacyanoferrate (II) and (III) ions adsorbed on Ag electrode surfaces. In the former case, five vibrational modes in the low-frequency range (214, 373,423,494 and 560 cm-') and four in the nitrilc-stretching region (2026,2067,2082 and 2122 cm-')
The surface structure and inhibiting properties of a benzotriazole (BTAH) derivative, dibenzotriazole-1-ylmethyloctylamine (DBTO), on a copper surface in 1 M sodium acetate solution (pH 5.8) were investigated by cyclic voltammetry, impedance spectroscopy and Raman spectroscopy. Raman spectra of pure
