An electron nuclear double resonance signal was detected, in sputtered deuterated amorphous material, that was attributed to the 2D nucleus. The frequency of the signal was found to be consistent with that estimated from the hyperfine interaction constant of a dangling bond with a 1H nucleus in amorphous hydrogenated material. It was concluded that these results provided further evidence for the existence of H-related or D-related dangling bonds.
