ABSTRACT

Spinrotation spectra of polycrystalline (NH4)3HfF7 in which radioactive181Hf was incorporated have been measured in the temperature range from −196 °C to + 70 °C. The spectra were interpretated on the base of the stochastic model of M. Blume. It was assumed that reorientations of the [HfF7]3− polyhedra take place at random. The resulting fluctuation rates can be understood as to be caused by an activation process. The activation energy was determined to 0.324(12) eV in agreement with NMR measurements on19F in this compound. More... »
