β¦ Synopsis
The presence of molecular hydrogen in a-C:H has been demonstrated by a series of neutron scattering experiments. Neutron diffraction gives a peak in the pair correlation function corresponding to the H-H bond distance. Inelastic neutron scattering experiments have shown peaks consistent with the H, rotation and stretch, and revealed details of the hydrogen environment.

A short summary is presented of inelastic neutron scattering studies of hydrogenated and deuterated amorphous silicon with particular emphasis on the structural role played by the hydrogen (deuterium) atoms. It is concluded that the data are consistent with the existence of molecular H, (D,) trapped
