Simultaneous realisation of hydrogen charging or discharging process and
in situ measurements of different NMR characteristic quantities give outstanding
chances for the investigation and understanding of local physical properties
of and hydrogen diffusion in disordered metal-hydrogen systems, including
both equilibrium and non-equilibrium states. A few selected preliminary experimental
results are presented in this letter for -H alloy on in situ
hydrogen concentration, proton NMR line-shift and magnetic susceptibility, 
NMR spectrum, spin-spin relaxation time and hydrogen diffusion activation energy
and correlation time measurements. The motional averaged spectrum is asymmetric
and the possible decompositions relate to the non-single-site residence of
hydrogen in this alloy.
