Data sets for "Transformations to the aluminum coordination environment and network polymerization in amorphous aluminosilicates under pressure"
Data sets used to prepare Figures 1, 3-22, S1 and S3-S13 in the Journal of Chemical Physics article entitled "Transformations to the aluminum coordination environment and network polymerization in amorphous aluminosilicates under pressure." The data sets describe the structure of amorphous aluminosilicates under, or recovered from, high-pressure conditions. They were obtained by using in situ high-pressure neutron diffraction and solid-state 27Al nuclear magnetic resonance (NMR) spectrocopy. The results are discussed by reference to those obtained from in situ high-pressure x-ray diffraction and solid-state 17O, 27Al, 29Si NMR experiments.
