摘要：

FT-Raman of solid state sample and surface enhanced Raman (SER) spectra of 5-(4-fluor-phenyl)-furan-2 carbaldehyde (5(4FP)-F-2C) at pH 1 were recorded and analyzed. The absence of carbonyl band in SER spectra was explained by the hydration of carbonyl bond. The shift by 5-10 cm(-1) of the surface enhanced Raman spectroscopy (SERS) bands and change in their relative intensity by comparing with the ordinary Raman spectrum (ORS) indicate the chemisorption of the sample molecules on the silver surface via the nonbonding electrons of the ring oxygen.
