High-pressure spectroscopic and diffraction studies confirm that hydrogen bonds can undergo symmetrization in various hydrogen-containing molecules and ionic phases under high pressure.

The analysis

The retrieved papers provide concrete evidence that high pressure induces hydrogen-bond symmetrization across different molecular and mineral systems, supporting the claim.
