Fully atomistic molecular dynamics(MD)simulations at 293,303 and 313 K have been performed for the four.component liquid crystal mixture,E7,using the software package Material Studio.Order parameters and orientationaltime correlation functions(TCFs)were calculated from MD trajectories.The rotational viscosity coefficients(RVCs)of the mixture were ca]culated using the Nemtsov-Zakharov and Fialkowski methods based on statistical-mechanicalapproaches.Temperature dependences of RVC and density were discussed in detall.Reasonable agreement between thesimulated and experimental values was found.
