Abstract

Proton spin-spin and rotating frame spin-lattice relaxation in Zn2Ni hydrides have been investigated. Activation energies for hydrogen motion were determined from Arrhenius plots of the relaxation times and found to be in general agreement with earlier NMR and PAC works. In common with previous studies of hydrides, asymmetric slopes about the relaxation minima are observed as well as adeviation from the motional narrowing behaviour at high temperatures.
