Abstract :
We report inelastic neutron scattering results on hydrogen adsorbed onto samples containing single-wall carbon nanotubes. These materials have attracted considerable interest recently due to reports of high density hydrogen storage at room temperature. Inelastic neutron scattering clearly shows the ortho–para conversion of physisorbed hydrogen in a nanotube containing soot loaded with hydrogen. From the rotational J=0→1 transition, no indication of a significant barrier to quantum rotation is seen.
