Rotational dynamics in the plastic-crystal phase of ethanol: Relevance for understanding the dynamics during the structural glass transition
(American Physical Society, 2000)
The reorientational dynamics within the rotationally disordered cubic plastic phase of solid ethanol is investigated by means of the concurrent use of computer molecular dynamics and quasielastic neutron scattering. Motions ...

1,1,3,3-tetramethylguanidinium dihydrogenorthophosphate
(International Union of Crystallography, 2000)
In the title compound, C 5 H 14 N 3 + H 2 PO 4 ˇ , the cation has a central guanidinium fragment with a planar geometry, as expected for a central C sp 2 atom with a small ...

Role of low-frequency vibrations on sound propagation in glasses at intermediate temperature
(American Physical Society, 2000)
We report measurements of the temperature dependence of the sound attenuation and the fractional change in sound velocity for the glass (G) and orientational-glass (OG) phases of polymorphic ethanol. Strikingly similar ...

Benzyltrimethylammonium dihydrogen orthophosphate monohydrate
(International Union of Crystallography, 2005)
The title compound, C 10 H 16 N + H 2 PO 4 H 2 O, crystallizes in the centrosymmetric space group P 2 1 / c with two independent molecules in the asymmetric unit. Therefore, nonlinear ...
