Vibrational spectral analysis of arcaine sulfate has been carried out using FT-IR, Raman, and SERS spectra. Raman and FT-IR spectra suggest protonation of the imino groups of the arcaine molecule at the expense of the proton from H{sub 2}SO{sub 4}. Analysis of SERS spectra shows that the molecule is adsorbed to the silver surface through the uncharged amino group and oxygen sites of the sulfate groups. The large enhancement observed for the amino group bending vibrations suggests that the molecule is adsorbed perpendicular to the silver surface.
