Elastic incoherent structure factors (EISFs) of benzene adsorbed in Na-mordenite zeolite as a function of scattering vector Q. Open circles represent the experimental data. Theoretical EISFs are shown for rotational diffusion (broken line), for uniaxial rotations of 2π/6 (full line) and for uniaxial rotations of 2π/3 (dotted line) [23].
