A method was investigated for obtaining the diffusion parameters from NMR measurements independently of the model that relates the spectral distribution to the nuclear relaxation time. The minimum value of the relaxation time T1dm and the temperature Tm at which it occurs was obtained for a series of TiHx samples over a wide hydrogen concentration range. The diffusion parameters were assumed to follow a relation of the form =P(x)oexp(-Ea/RT) where the only concentration-dependent factor is a probability function P(x). The form of P(x) was investigated and the concentration dependence of T1dm was seen to agree to within 2% of that predicted by Barton and Sholl.
