| Abstract: | The surface enhaced Raman scattering of pyrazine in a silver sol was investigated. Strong enhancement of the g modes and appearance of Raman forbidden vibrations were observed, in agreement with existing results obtained on electrode surface. Chemical reactions of pyrazine on Ag were monitored by Raman and mass spectroscopy. |
