Abstract

The results of recent experiments which indicate that surface-enhanced Raman scattering from molecules adsorbed on coldly evaporated silver films is associated with cavity sites is interpreted as an electromagnetic field enhancement in regions enclosed by several silver grains. No such enhancement is obtained for a wedge geometry. Cavity sites are seen to be also strong enhancement centers for resonance optical phenomena such as fluorescence and photochemical yield.
