Popis: The technique of vacuum UV Raman spectroscopy is applied to diamond-like carbon (a-C:H) films in order to study the state of hydrogen non-bonded with host carbon atoms. Under resonant excitation, a series of Raman bands related to rotational levels of a stretched H2 molecule is observed. The data are used to estimate the parameters of the H2 molecule in a-C:H. A model of the reversible transfer of hydrogen between the molecular state and states bonded to carbon is discussed.
