were studied using Fourier
transform infrared (FT IR), Fourier transform Raman (FT
RS), and surface-enhanced Raman (SERS) spectroscopies.
Analysis of obtained FT IR and FT RS spectra show that all
investigated compounds in the solid state exist as dimeric species formed by an H-bonding interaction between

moieties of each monomer. In addition, comparison of the wavenumbers, intensities, and broadness of bands from the FT Raman
and SERS spectra allowed information to be obtained regarding the adsorption geometry of the investigated compounds
immobilized onto an electrochemically roughened silver substrate.
