摘要：

We have, by use of inelastic neutron scattering, detected the presence of molecular hydrogen in amorphous hydrogenated car-bon. We have found the hydrogen to be in a high-pressure, asymmetric environment formed by the compressive stresses in the a-C: H films. On comparing two samples, we have also found that the sample with higher molecular hydrogen concentration has a lower total hydrogen composition. This is caused by a higher network density, trapping the molecular hydrogen during network growth.
