We request 7 days on VESUVIO to study the molecular crystals 7Li(NH3)4X (X=I, Br, Cl , F) and parent halides, 7LiX (data for 7LiF and 7LiCl already exists). This proposal is tied to a TOSCA and IRIS proposal. As part of an EPSRC funded research project, we wish to study the dynamics of ammonia in coordinated halide complexes, from the long-timescale through to sub-femtosecond dynamics. We wish to use VESUVIO for the study of the spherically averaged proton momentum distributions, determination of mean kinetic energy as it changes with chemical environment. We also wish to utilise the capability of VESUVIO in examining both Li and N mean kinetic energies in addition to the proton.
