| Abstract: | The SERS spectra of pyridine–Cn (n=1–6) complexes are investigated theoretically. The obtained enhancement factors of about 102–103 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. |
