Abstract

Adsorption of trans-cinnamonitrile on the metal surface in silver sol has been investigated by the surface-enhanced Raman scattering technique. The molecule is found to adsorb on the surface via its nitrogen lone pair electrons. In the absence of coadsorbed chloride ions, the molecule is converted to trans-cinnamic acid by a surface reaction. When a small amount of sample is irradiated with a laser, a surface photoreaction of trans-cinnamonitrile is observed.
