Abstract: | Cyclic voltammetry and in situ FTIR spectroscopy were combined to study irreversibly adsorbed cyanide adlayers in both perchloric and sulphuric media. Cyanide adlayers were formed on Pt(111) single-crystal electrodes and are stable in a wide range of potentials. A vibrational band at around 2100 cm−1 was assigned to the C–N stretching vibration of adsorbed cyanide, for which tuning rates close to 100 cm−1 V−1 below 0.5 V and 30 cm−1 V−1 above this potential were measured. These values are independent on the supporting electrolyte employed. A reorientation of the adsorbed cyanide was proposed to explain the changes observed in both tuning rate and integrated intensity at around 0.5 V. |
