Abstract
The Raman spectrum of sulphonated copper phthalocyanine on a silver electrode surface is reported for four excitation wavelengths in the Q-band region at voltages between +0.6 and -0.6 V (vs SCE). SERS activity is observed and the bonding and orientation of the surface species are voltage dependent and are inferred from a vibrational analysis. Maximum scattering intensity is observed at -0.2 V (vs SCE) and is attributed to molecules bonded edge-on to the surface through SO3- groups.
