Abstract
This article reviews recent high-pressure Raman and Brillouin studies of hydrogen-bonded molecular crystals. Results on selected materials, with a view to illustrating the high-pressure physics for the hydrogen bond, are presented and discussed: HF as the one-dimensional hydrogen-bonded system, HCONH2 as the two-dimensional system, H2O as the three-dimensional system, and H2S as the hydrogen-bonded system in the plastic phase.
