Applying pressure to hydrogen-bonded crystals hydrogen bromide and hydrogen sulfide alters significantly the bonding nature and induces various kinds of phenomena: order-disorder transition, hydrogen-bond symmetrization, and molecular dissociation accompanied by the solid-state reactions. This article reviews the relationship between pressure-induced structural phase transitions and solid-state reactions, revealed from the cooperative works between high pressure experiments and the ab initio molecular dynamics simulations.
