An excitation profiie investigation of 3,3'diethyl-2.2'-benzthiatrimethinecyanine adsorbed on silver sol shows, for the pure surface enhancement, a relative minimum near thedye absorption (about 550 nm) and a strong increase for yellowred wavelengths, which is esphined qualitatively in terms of an "

This paper emphasizes the observation of SERS spectra of aniline violet, aniline red, eriochrome black T and phenolphthalein on silver sol and a qualitative explanation of the relationship between SERS spectra and molecular vibrational modes.
