Dynamics within the Plastic Crystal Phases of Hydrogen Chloride


Hydrogen chloride exhibits a complex phase diagram account made of its simple molecular structure. Three crystalline phases are known to exist at ambient pressure below its melting point, two of which are plastic. This material has also been the focus of renewed attention due to the availability of ab-initio computational tools able to deal satisfactorily with details of the structure and dynamics that are impossible to reproduce via the use of classical molecular dynamics simulations. In contrast to this surge of new theoretical interest, experimental data on the dynamics are scarce. In the present proposal, we aim to bridge the above gap between theory and experiment by carrying out a comprehensive study on the stochastic motions in plastic hydrogen chloride by means of quasielastic and inelastic neutron scattering.
