Zusammenfassung:
We calculate from ab initio molecular dynamics the Raman
scattering of high-pressure ice. To this effect we apply a new
method based on the Berry phase theory of polarization. Our
results are in agreement with recent and difficult experiments
and are compatible with a picture in which ice VII is a proton-
disordered system and in ice X the hydrogen bond is symmetric.
