Magnetic resonance D 6560Molecular H2 Trapped in AlH3 Solid. -AlH3 samples are characterized by static and MAS NMR spectroscopy, and neutron scattering. A comparatively narrow feature in the proton NMR spectrum is due to H2 trapped within the solid, presumably from earlier processing procedures or partial decomposition. Similar NMR signatures in other hydrogen-storage solids such as NaAlH4 may also be due to trapped H2. -(SENADHEERA, L.; CARL, E. M.; IVANCIC, T. M.; CONRADI*, M. S.; BOWMAN, R. C.
