Our joint QENS experiments/MD simulations strategy has proved to be a valuable tool for providing a complete picture of the diffusion mechanism for short-length alkanes in a MOF-type material. A detailed analysis of the translational and rotational dynamics from the QENS spectra highlighted that all alkanes follow a 1D-type diffusion gliding along the tunnel of the MIL-47(V) solid, with either isotropic or uniaxial rotation depending on the chain length. Spectacular blowgun-type diffusion has been further evidenced for n-butane from a higher diffusivity at low loading of this alkane compared with propane. The understanding gained here on the chain-length dependence of n-alkanes diffusion in a model rigid MOF could be of great interest in the field of the alkane separation processes that are known to be significantly governed by transport kinetic criteria
