• The chemical treatment of single wall carbon nanotube (SWNT) samples leads to a modification of their vibrational and electronic properties. We here report the alteration of the Fermi level of SWNTs chemically modified with Ag and CrO 3 as observed in the resonance Raman spectra of both metallic and semiconducting SWNTs. Our results indicate that while Ag behaves as an electron donor, CrO 3 behaves as an electron acceptor for SWNTs.
