Popis: | The results of inelastic neutron scattering experiments on ytterbiumhexaammine are presented. At temperatures below 35 K, the dominant dynamical process is a uniaxial rotation of the ammonia in hindering potentials of about 35 meV. At higher temperatures, another type of ammonia motion is observed, which is described as reorientations of entire Yb(NH3)x complexes (x≊6). |
