Abstract

The magnitude of the plasma-resonance contribution to surface-enhanced Raman scattering on silver-island films has been measured with use of an experimental arrangement in which the resonance can be suppressed. The measured reduction in Raman scattering is 300, but theoretical analysis indicates that there may remain an additional unsuppressed factor 3. The data show that plasma resonances are not essential for observation of Raman scattering by molecular monolayers using standard detection techniques.
