Abstract

Vibrational spectra for single wall carbon nanotubes, double wall carbon nanotubes, single wall carbon nanohorns and C ₆₀-peapods have been measured with inelastic neutron scattering in a wide range of energy transfer, 5-220 meV. A decrease in intensity around 75-100 meV and the appearance of two peaks around 120-125 meV and 150 meV in the double wall nanotubes and C ₆₀-peapods spectra compared to single wall carbon nanotubes and nanohorns were observed. These findings indicate the possibility of strong interaction between the walls of the double wall carbon nanotube, and between C ₆₀ molecules and carbon nanotube of the peapod. Alternatively, a possible contamination of the samples by hydrogen (even in microscopic quantities) covalently bonded to the carbon also can account for the observed phenomena.
