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.
