	Article:	SURFACE-ENHANCED RAMAN SPECTROSCOPY OF 5-(4 BROM-PHENYL)-FURAN �2 CARBALDEHIDE ON SILVER SOL. Authors: T. ILIESCU, FLORIN-DAN IRIMIE, M. BOLBOACA, CSABA PAIZS, IOAN BRATU, R. PACURARIU, WOLFGANG KIEFER.


	Abstract: FT-Raman and SER spectra of 5-(4-brom-phenyl)-furan-2 carbaldehide at pH 1 were recorded and analyzed. The absence of carbonyl band in SER spectrum was explained by the hydration of carbonyl bond. The shift by 5-13 cm-1 of SERS bands and change in their relative intensity by comparing with ordinary Raman spectrum, indicate the chemisorption of the sample molecules on the silver surface via the nonbonding electrons of the ring oxygen.
