Abstract

Ultraviolet Raman scattering is used to study the state of hydrogen in diamond-like α-C:H. Scattering lines are observed corresponding to transitions between the rotational states of the hydrogen molecule. The interaction with the α-C:H matrix increases the internuclear distance and perturbs the electronic-vibrational terms of the H2 molecule, so that resonance Raman scattering can be observed, excited by 10.04 eV photons.
