Molecular dynamics simulation of norbornene plastic crystal

Abstract

Molecular dynamics simulations have been performed on the norbornene plastic crystal in the temperature range 125–320 K. This investigation shows the existence of a remarkable dynamical crossover in the pico–nanosecond regime at the temperature T A≃200 K consistent with previous NMR and muon spin rotation experiments performed on the same compound. This temperature corresponds to the onset of non-exponential relaxation and non-Arrhenius behavior very much in keeping with recent views proposed for supercooled liquids.
