N2 - A detailed profile deconvolution analysis was carried out for the concentration-dependent surface-enhanced Raman scattering spectra of 4,4'-diaminostilbene. The spectral signatures of the molecules located inside and outside hot spots regions were assigned. A resonance character of Raman enhancement accompanied by a charge transfer was revealed for the molecules adsorbed in the hot spots whereas it was absent on the uniformly amplifying surface.
