Abstract
The total structure factor for deuterated ammonium chloride measured by neu
tron diffraction has been modeled using the reverse Monte Carlo method. The
results show that the orientational disorder of the ammonium ions consists
of a local librational motion with an average angular amplitude alpha = 17
degrees and reorientations of ammonium ions by 90 degrees jumps around two
-fold axes. Reorientations around three-fold axes have a very low probabili
ty. (C) 1999 Elsevier Science B.V. All rights reserved.
