Description
The Raman spectra of ammonia solid I and II were studied
in the lattice and intramolecular region. The study of the internal modes of phase I suggests the presence of
disorder in the ordered phase. The lattice modes of
phase II are, for the first time, carefully reported as
two very broad lines superimposed on an overdamped
feature. The results confirm the structure previously
determined by neutron scattering and NMR that phase II is
a typical disordered phase with space group P6,3/mmc. A
mode assignment was tentatively made and Gruneisen
parameters of the two assumed translational modes
calculated. In terms of the Michel-Naudts theory of
rotational-translational interactions, phase II is in the
slow relaxation regime. A four-band model was used for
the intramolecular stretching region.
