Abstract:
FT-IR and FT-Raman spectra of orthanilic acid were recorded and analyzed. Surface-enhanced Raman scattering (SERS) spectrum was recorded on a silver electrode surface. The vibrational wavenumbers were computed by the ab initio method using HF/6–31G* basis and they were found to be in good agreement with the experimental values. Potential dependence of the SERS profile was studied. The profile was prominent at electrode potentials of −0.3 and −0.8 V. The selective enhancement of different bands showed a change in orientation of the molecule on the silver surface. Copyright © 2006 John Wiley & Sons, Ltd.
