The 1H and 2H spin–lattice relaxation times in the monohydride phase of the V–H–D and Ti0.1V0.9–H–D systems were re-analyzed using Bloembergen–Purcell–Pound equations, with a log-normal distribution of the correlation times, and the resultant parameters were compared with those for the Ti0.33V0.67–H–D system. The mean activation energy and the magnitude of the distribution of H and D diffusions were considered with regard to the metal composition, the H site, the crystal structure and the [H]/[D] ratio.
