Elusive plastic phase of Ice at the boundary of liquid water and Ice VII on dynamic compression of water

Numerous investigations (both numerical and experimental) have demonstrated phase transformation of liquid water to that of ice VII “like” crystal structure upon dynamic compression. The diagnostics used in most of these experimental investigations include refractive index changes, electrical conductivity changes and/or dielectric changes from which the crystal lattice structure can be somewhat estimated. However, no detailed inter and intra molecular studies are done to characterize the observed phase of ice upon dynamic compression of liquid water. Translational and rotational diffusion characteristics of the resultant crystal structure are done to demonstrate the presence of the elusive plastic phase of ice typically hypothesized to be present at the boundary of the liquid water and ice VII.
