Neutron Diffraction Studies of Ices and Ice Mixtures
The ices are model systems for the study of weak interactions — most notably the hydrogen bond — which are applicable to fields as diverse as biology and planetary modelling. High-pressure studies provide a powerful means to access the density dependence of the interactions but prior to 1990 it was not possible to determine accurately the location of the hydrogen atoms at high-pressure because neutron diffraction was generally limited to pressures below 3 GPa. This chapter describes highpressure neutron diffraction studies of a range of ices and the new information that these studies have provided.
