摘要：
Fourier transform infrared (FT-IR) spectra were measured for 2,2'-bipyridine (bpy) adsorbed on silver fine particles derived from colloid and bis (2,2'-bipyridine) silver( I) nitrate ([Ag-I(bpy)(2)]NO3) by using an attenuation total reflection (ATR) prism. The surface enhanced infrared spectra of bpy showed drastic changes in the intensities of bands due to ring stretching vibrations and CH bending vibrations. This suggests that the adsorbed molecules on silver particles take a conformational change and the intramolecular charge-transfer, which are different from those of the crystal.
