Research Abstract

Classical molecular dynamics simulations with two kinds of model potentials have been performed in order to investigate interrelationship between free volume and the 2nd-rank orientational relaxation time near the isotropic-nematic transition point. We have discussed on the relationship with molecular shape, pressure and potential dependences on the molecular reorientational relaxation time.
