  Abstract:  FT Raman and SER spectra of 5-(3-nitro-4-methyl-phenyl)-furan-2 carbaldehide at different pH values were recorded. A theoretical vibrational analysis was made and compared with FT Raman spectra. At low pH values both samples present a good SER spectra. The shift to red of SERS bands by 10-15 cm-1 is an indication of chemisorption of these species, which are bonded to the silver surface via nonbonding electrons of ring oxygen.
