Abstract

We report on single-wall carbon nanotube (SWCNT) specific $^{13}$ C isotope enrichment. The high temperature annealing of isotope enriched fullerenes encapsulated in SWCNTs yields double-wall carbon nanotubes (DWCNTs) with a high isotope enrichment of the inner wall. The vibrational spectra evidences that no carbon exchange occurs between the two walls. The method facilitates the identification of the Raman signal of the outer and inner tubes. Nuclear magnetic resonance proves the significant contrast of the isotope enriched SWCNTs as compared to other carbon phases, and provides information on the electronic properties of the small diameter inner tubes of the DWCNTs.
