Single molecule demonstration of Debye–Stokes–Einstein breakdown in polystyrene near the glass transition temperature
Abstract
Experiments with high-molecular-weight polystyrene provide insights into the mechanisms behind rotational-translational decoupling in glassy systems. Specifically, particularly mobile molecules exhibiting anisotropic trajectories are found to play a key role in Debye-Stokes-Einstein breakdown.
