Notes:
A scanning Raman spectrometer and an Nd: YAG laser operating at 1.06 μm were used to observe the surfaceenhanced Raman scattering (SERS) of pyridine in yellow silver colloids. Enhancement factors for the triangle ring breathing vibration mode at 1006 cm-1 and for the totally symmetric breathing mode at 1036 cm-1 are about 16.5 and 21 times larger, respectively, than those found for excitation at 514.5 nm. The large enhancement factors for excitation in the near-infrared region suggest that further refinement of the theories currently proposed to explain the SERS effect is necessary.
