摘要: Abstract The surface coverage of halide ions on Ag is found to be the most dominant factor determining potential dependence Cl-Ag Raman intensity and mode energy. observed signals are predominantly associated with active sites which stabilized by coadsorbed ions. identified as intrinsically resonant clusters. resonance in clusters gives rise short-range enhancement scattering this situation. We compare our experiments other recently results point out why uncorrected magnitude not a simple measure adsorbed chloride.
