Nuclear Magnetic Resonance in Polycrystalline UF6

摘要

An F19magnetic resonance study of polycrystalline uranium hexafluoride as a function of temperature and magnetic field is presented. The low temperature spectra are resolvable into two symmetric components, demonstrating the existence of two nonequivalent sets of Usngbnd;F bonds. At higher temperatures the two resonances coalesce in spite of the fact that the magnetic susceptibility of UF6is temperature independent. The possible origin of this effect is discussed.
