Abstract
The Raman signal of hydrogenated and deuterated amorphous carbon-films, respectively, is dominated by the resonance Raman spectrum ofπ clusters. Loss of H and D by thermal annealing sharpens and shifts Raman bands analogous to the case of annealing of amorphous carbon and ion bombarded graphite. H +2 and D +2 bombarded graphite displays a weak signal assigned to diamond clusters.
