Abstract We report the surface enhanced Raman scattering (SERS) from pyridine in Ag colloids by Fourier transform (FT) infrared Raman spectrometer. The enhancement factors were estimated as 3.4x10⁵ for pyridine in Ag colloids and 5.4 x10⁵ for the same sample but with the addition of a small amount of KCl. The considerable enhancement in infrared indicates the necessity of further refinement of the currently proposed SERS models.
