Abstract

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.

## Abstract Surface‐enhanced Raman spectra of 2‐mercaptobenzoxazole (MBO) adsorbed on silver hydrosol were obtained. From the comparison of the SER and normal Raman spectra, both in the solid state and in NaOH solution, it can be deduced that the molecule is dissociatively adsorbed on the silver so
