Surface-enhanced Raman spectra of pyrazinecarboxamide and pyrazinecarbonitrile on silver sols

Adsorption of pyrazinecarbonitrile and pyrazinecarboxamide on the metal surface in silver sols was investigated by the surface‐enhanced Raman Scattering (SERS) technique. Both molecules give similar spectra because the nitrile is converted into the amide by surface reaction. Pyrazinecarboxamide was...

Zusammenfassung:	Adsorption of pyrazinecarbonitrile and pyrazinecarboxamide on the metal surface in silver sols was investigated by the surface‐enhanced Raman Scattering (SERS) technique. Both molecules give similar spectra because the nitrile is converted into the amide by surface reaction. Pyrazinecarboxamide was found to adsorb via the substituent group with edge‐on orientation.
