Abstract
Inelastic neutron scattering has been used to investigate the influence of
different guest molecules, G, on the rotational hindering potential for NH3
in Hofmann clathrates Ni(NH3)(2)Ni(CN)(4). mG. Non-polar guests (benzene a
nd biphenyl) lead to quasi-free rotor environments. For polar guests (water
, aniline, phenol, dioxane), dipolar interactions give rise to an increase
of the rotational barrier; most often, complex spectra result from statisti
cal orientational disorder of the guest molecules. (C) 2000 Elsevier Scienc
