Inelastic neutron-scattering experiments have been performed for the first time on glassy phosphorus-selenium alloys. The effective density of vibrational states so obtained is highly structured in the case of glassy P0.67Se0.33 and provides evidence for the existence of molecular clusters in the structure based predominantly on P4Se3 units, i.e., a "zero-dimensional" glass.
