โœฆ Synopsis


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 "electromagnetic" model.

SJZRS on silver sol has been demonstrated to be an attractive and simple spectroscopic tool for transition-metal complexes. The SERS spectra of [Cr(bpy),)3+ on Ag sol are more similar to the solution Raman spectra of [Fe(bpy)3]2' or [Ru(bpy)3]2' than to that of [Cr(bpy)~])+, which gives a strong hin
