Figure 1: Neutron diffraction data.
From: Encapsulation kinetics and dynamics of carbon monoxide in clathrate hydrate

Time-dependent neutron diffraction patterns showing carbon monoxide clathrate formation. The diffraction patterns collected at 173 bar after 1, 2.5 and 17 weeks are from one synthesis run. The patterns collected at 173 bar after 5 weeks and at 100 bar after 17 weeks are from another synthesis run. The conditions shown in the figure are the synthesis pressures and temperatures. All neutron diffraction data were obtained at 260 K and at indicated pressures.
