 Abstract: We present an investigation of the kinetics of adsorption and desorption of some weakly bonded gases from single wall carbon nanotube bundles and - for comparison - from graphite. Thermal desorption spectra from CH4, Xe and SF6 as well as those of MeOH, EtOH and H2O can be used to obtain adsorbate binding energies. The observed trends in the binding energies of gases with different van der Waals radii suggest that so-called groove sites on the external bundle surface are the preferred low coverage adsorption sites due to their higher binding energy. These results shed new light on the wetting properties of SWNT bundles. In addition we find that measured sticking coefficients can be related to the diffusion kinetics of adsorbates into the bulk of the nanotube samples.
