The dynamics of low molecular weight polyisoprene was investigated over a broad temperature window using dielectric relaxation spectroscopy and pulsed field gradient nuclear magnetic resonance. Molecular dynamics simulations performed using two different models captured very well the dynamic properties documented experimentally. Experimental data and a normal mode analysis on simulation trajectories showed that chain dynamics over the molecular weight and temperature range studied could be described well by the Rouse model.
