Abstract
The optical absorption of films having a variety of structures was studied: in no case was a second resonance peak observed. However, calculations based on an ellipsoidal particle model taking into account the absorption characteristics of bulk gold suggest that, for gold films, only one peak would be resolvable. The wavelength of this absorption peak was correlated with a structure factor for the film which was then used to compare the predictions of particle shapes by several theories.Keywords
