Surface enhanced Raman spectrometry (SERS) of copperphthalocyanine (CuPc) in silver hydrosol is reported. The solvent effect on the Raman activity of the adsorbate is discussed in terms of co-adsorption and replacement kinetics of the solvent molecul

Surface-enhanced Raman scattering (SERS) of hypoxanthine (HX) molecule on silver colloid confirms that the molecule in the surface adsorbed state exists as [keto–N9 H9] form at acidic and normal pH but as [enol–O6 H1, N9 H9] form at alkaline pH.

Surface enhanced Raman spectra (SERS) of 2-chloro and 3-chlorothiophene molecules in silver sol have been investigated. It is observed that though the molecules are principally adsorbed on the metal surface through the sulfur atom, the chlorine atom

Surface enhanced Raman spectra (SERS) of 2- and 3-bromothiophene molecules in silver sol are compared with those of molecules in acetonitrile solution. The experimental results suggest that the 2-isomer is adsorbed on the metal surface through both t

Raman scattering from ortho-, meta- and para -phenetidines in solution and in surface adsorbed state on colloidal silver have been investigated. Comparison of the spectra in solution and in silver sol shows large enhancement of the Raman scattering f

Raman spectra of 2-, 3- and 4-acetylpyridines (AP) are obtained in bulk phase, in aqueous solution and in the adsorbed state on colloidal silver particles. Addition of the acetylpyridines on the Ag-sol results in aggregation of the silver particles s

Surface enhanced Raman (SER) spectra of samples in silver sole have been used to monitor the relative concentration of protonated and neutral pyridine-4-carbaldehyde (4PCA) on the silver surface, which is shown to depend on the solution pH. At low pH
