The properties of liquid nitrogen

Abstract

A Molecular Dynamics simulation of liquid nitrogen has been carried out using an atom-atom potential together with a point quadrupole-quadrupole interaction. The changes in the properties of the model fluid compared to a previous simulation [1] using the atom-atom potential alone are small but significant. The structure factor is notably closer to experiment. The properties associated with reorientation motion are also closer to experiment but discrepancies remain especially at high temperatures.
