Abstract
The structures of ammonium halides ND4I and ND4Br have been studied by mean
s of neutron diffraction at pressures up to 9 GPa. We found that the high-p
ressure phase V of ammonium halides has the same structure as the low-tempe
rature phase III-tetragonal one with antiparallel ordering of ammonium ions
. Vibrational spectra of NH4I have been studied at pressures up to 5 GPa. L
ibration and transverse optical mode frequencies as functions of pressure w
ere obtained. (C) 2000 Elsevier Science B.V. All rights reserved.
