Here we report the quasi elastic neutron scattering (QENS) study of the dynamics of 1,3-butadiene molecules adsorbed in Na–Y zeolite at saturation loading. Data analysis showed that the adsorbed 1,3-butadiene molecules undergo motion, which could be described by jump diffusion model. Within this, various plausible theoretical models have been considered to describe the experimentally observed data. Residence time and the jump length are evaluated for all the models considered. The diffusivity values obtained for the three models are found to be consistent within themselves and also while compared with those obtained for other guest molecules studied earlier.
