title: Theoretical investigation on SERS of pyridine adsorbed on Cn clusters induced by charge transfer: a hint that SERS could be applied on many materials.
abstract: The SERS spectra of pyridine-C(n) (n=1-6) complexes are investigated theoretically. The obtained enhancement factors of about 10(2)-10(3) in the pre-resonance Raman spectrum calculations are attributed to charge-transfer transitions from the carbon clusters to pyridine, where a good match of band structures between substrates and probe molecules is essential.
