Monitoring molecular motion in nano-porous solids

In this article, the important role of neutron spectroscopy techniques for the study of the dynamics of molecules hosted inside cavities at the nanometer scale is described. Three different complex systems are highlighted: alkanes with variable length inside zeolitic matrices, C60 fullerene chains inside single wall carbon nanotubes, and inert gas (N2, Xe) molecules inside water clathrates.
