| Abstract |
Surface-enhanced Raman scattering (SERS) spectroscopy was applied to vibrational characterization of thionine and several other phenothiazine dyes adsorbed on silver colloids in order to discern the spectral vibrations among phenothiazine dyes with different methyl substitutions. FT-Raman spectra of powder form of the dyes were also obtained for comparison with the SERS spectra. Density functional theory calculations were performed to aid vibrational assignments of the observed bands and to determine the adsorption structure of dyes on the silver surface. The interaction of dye adsorbates with different methyl substitutions with the metal surface leading to different adsorbate conformations and molecular structures were discussed based on the changes in the observed SERS spectra. |
