Deuteron and proton NMR measurements have been made on a plasma-deposited a-Si: (D,H) sample. The spin-lattice relaxations include resolvable contributions arising from relaxations which proceed via molecular orthohydrogen and paradeuterium impurities. Several alternate relaxation mechanisms are considered. The deuteron resonance shows two distinct components, one of which exhibits a long spin-lattice relaxation time T₁ and a 66-kHz quadrupole-split resonance doublet line shape, which is shown to be characteristic of D bonded to Si.
