## Abstract Diffusion of gases in polymers below the glass transition temperature, __T__~g~, is strongly modulated by local chain dynamics. For this reason, an analysis of pulsed field gradient (PFG) nuclear magnetic resonance (NMR) diffusion measurements considering the viscoelastic behavior of po
