	Detailed\&nbsp;measurements\&nbsp;of the\&nbsp;photochemical\&nbsp;and photophysical\&nbsp;properties\&nbsp;of an adsorbate on discontinuous metal-island\&nbsp;films\&nbsp;are used to explore the unusual electrodynamics near rough\&nbsp;metal surfaces.\&nbsp;Several aspects of the\&nbsp;properties\&nbsp;have been\&nbsp;measured:\&nbsp;the magnitude the temporal decay of the\&nbsp;fluorescence,\&nbsp;the shape and temporal evolution of the\&nbsp;fluorescence\&nbsp;spectrum,\&nbsp;and the effects on the\&nbsp;spectrum\&nbsp;of a\&nbsp;photochemical\&nbsp;hole-burning process. Dramatic increases in the fluorescent decay rate and decreases in the\&nbsp;photochemical reaction\&nbsp;rate as well as systematic\&nbsp;spectral shifts\&nbsp;of the emission of molecules experiencing the different electrodynamic environments on the island\&nbsp;film\&nbsp;are observed. These results reveal the strong effects of the coupling between the adsorbate and the plasma resonances localized on the islands of the\&nbsp;film.\&nbsp;We model our results using the electrodynamic picture which has successfully described many aspects of surface-enhanced Raman scattering and other optical processes on island\&nbsp;films.\&nbsp;The excellent agreement between this model and our results suggests that an important feature of the electrodynamics at these rough\&nbsp;metal surfaces\&nbsp;is the dipolar character of the couplings between the surface, the adsorbate, and the optical fields.
