Abstract
Two adsorbate forms of the monothiocyanate complex of chromium ion on the silver electrode are identified in the surface enhanced Raman scattering. The spectroscopic, especially the electronic, properties of these two forms under different applied voltages on the electrode and under both 632.8 and 514.5Â nm excitations are studied by the bond force constants (bond orders) and the bond polarizability derivatives which are retrieved from the Raman intensities by an algorithm developed by Wu and co-workers [B. Tian, G. Wu, G. Liu, J. Chem. Phys. 87 (1987) 7300]. The work shows the potential of this approach to the surface enhanced Raman scattering and other fields like resonance Raman that involve vibronic coupling.
