The structures of molecular monolayers and films can be elucidated by studying the unique linear and nonlinear optical properties of small metal islands deposited on the films. The islands can lead to surface-enhanced electromagnetic effects as their size and separation are much smaller than the wavelength of light, and these effects have been studied using spectrophotometry and optical microscopy.
