| Description
| - Technique of Surface-enhanced Raman scattering (SERS) spectroscopy is a suitable analytical tool to study compounds adsorbed on Ag, Au or Cu surfaces. In-situ SERS spectroelectrochemistry allows investigation of surface intermediates in dependence on applied potential. Riboflavin, which interaction with surface has been studied in this work, is a compound of the vitamin B group. The investigation of riboflavin molecules orientation was carried out in special spectroelectrochemical cell using dispersive Raman spectrometer with laser excitation at 785 nm. Aqueous solution (0.1 M KCl) of riboflavin (10-5 mol.L-1) was used as electrolyte and deposition bath simultaneously. In-situ SERS spectra of riboflavin adsorbed on the surfaces were recorded potential value from +100 mV to -1100 mV with step 100 mV. From selection rules of SERS it is known that vibration modes perpendicular to the surface and located close to the surface are the most enhanced. We observed that bands intensities and their ratios were changing significantly with respect to potential values and metal used. Orientation of adsorbed riboflavin molecules depends on varying applied electrode potential. Spectra of various orientations of riboflavin molecules were compared with theoretically calculated spectra of riboflavin located in close vicinity of Ag, Au and Cu surfaces.
