Hydrogen diffusion behavior and electronic properties of crystalline TiCuH/sub 0/ /sub 94/, Ti/sub 2/CuH/sub 1/ /sub 90/, and Ti/sub 2/CuH/sub 2/ /sub 63/ and amorphous a-TiCuH/sub 1/ /sub 4/ are studied using proton relaxation times, proton Knight shifts, and magnetic susceptibilities. Crystal structure and hydrogen site occupancy have major roles in hydrogen mobility. The density of electron states at E/sub F/ is reduced in amorphous a-TiCuH/sub 1/ /sub 4/ compared to the crystalline hydrides.
