The structure of liquid and supercritical deuterium fluoride from neutron scattering using high-pressure techniques

Abstract

We present neutron diffraction data for deuterium fluoride at two liquid and four supercritical states in the temperature range of 300–473 K and for pressures up to 320 bar, spanning a factor of 4 in sample density. The intra- and intermolecular parts of the measured structure factors were separated and conclusions about the temperature and density dependence of the intra- and intermolecular structure are deduced. © 2000 American Institute of Physics.
