| Abstract: | Surface-enhanced Raman scattering (SERS) spectra of 2-cyanopyridine (2 CP) adsorbed on silver colloidal particles have been
investigated. The prominent SERS bands are observed at 556, 612, 778, 1002, 1060, 1072, 1150 and 1240 cm−1. The absolute enhancement factor of the Raman signals in SERS studies has been estimated to be of the order of 102–105 for various bands. The 2CP molecules have been ascribed to adsorb on colloidal particles in standing up fashion. |
