Abstract
Near-infrared Raman spectroscopy has been used to obtain Surface-Enhanced Raman Spectra (SERS) of pyridine on both silver and gold electrodes. The enhancement factor is higher than that found for visible excitation, and the band intensities are somewhat different. There is no indication of photochemical damage or change of the sample when near-infrared radiation is used, even at relatively high power levels.
