Surface picosecond raman gain spectroscopy of a cyanide monolayer on silver

Abstract A new surface picosecond Raman gain technique is used to measure the Raman spectrum of a monolayer of CN on silver. A new result, not obtainable from conventional Raman techniques, emerges from this study of the enhanced Raman effect on silver surfaces the smooth continuum that accompanies enhanced Raman scattering is luminescence, not a Raman effect.
