Isomerization of merocyanine chromophores in a self-assembled monolayer (SAM) on a gold substrate was examined by means of visible-UV reflection spectroscopy. Anomalous peaks and/or dips observed in the spectra were ascribed to the loss of the metallic character of gold at the wavelength region shorter than 500nm. Spectral simulations based on the Lorentz oscillator model revealed that the merocyanine SAM undergoes isomerization even in a densely packed monolayer.
