Transport properties of liquid hydrogen fluoride

The dynamical properties of liquid hydrogen fluoride are investigated by a molecular dynamics study of the correlation functions relevant for a generalized hydrodynamics description of transport coefficients. The results are compared with the corresponding ones in liquid water in order to understand the role of hydrogen bonding in the two systems. The different behavior can ultimately be attributed to the arrangement of the molecules, which form irregular chains in HF and a tetrahedral network in water. For the two systems, the differences between experimentally measurable quantities are also pointed out and discussed. (C) 2000 American Institute of Physic
