THE STUDY OF ADSORPTION MODEL FOR 4,4′-BIPYRIDINE ADSORBED AT THE CHEMICALLY DEPOSITED SILVER FILM BY SERS

This paper presents the SERS spectru spectrum of 4,4′-bipyridine adsorbed at the chemically deposited silver filem.Comparing with the normal Raman spectra of 4,4′-bipyridine in the solid state and in 0.5 mol/L methanol solution ,we have studied the SERS spectrum and further discussed the adsorption model for 4,4′-bipyridine adsorbed at the chemically deposited silver film,and also explained the experimental results with image field mode,Experimental results show that 4,4′-bipyridine adsorbed at the chemically deposiled silver ilm via N-atom of pyridinering (Upright).
