The hydrides of these metals were studied by using H nuclear magnetic resonance spectroscopy. The Fourier-transformed spectra and spin-spin and spin-lattice relaxation times were measured at temperatures of between 77 and 400K. The addition of Ni caused the number of H atoms on 0z2 sites to decrease, and the H superstructure to change. The Ni additions had differing effects above and below 200K (table 180), and the diffusion mechanism was presumed to change at that temperature.
