title: Vibrational spectra of saccharin nitranion and its orientation on the surface of silver metal particles.
abstract: Infrared-reflectance spectra of the saccharin nitranion adsorbed on silver powder was observed. Surface-Enhanced Raman Scattering (SERS) spectra of the saccharin nitranion were also recorded using cellulose acetate films doped with fine silver particles. The spectra suggested that the saccharin nitranion is bonded to the silver metal surface through the oxygen atom of carbonyl and the nitrogen atom of the imide ring groups and that the nitranion tilts at the surface.
