It is shown that the IR emission spectrum in objects as the Orion ridge is compatible with the presence of two- to five-ring linear PAH species in amorphous carbons (specifically, the derivatives of naphthalene, anthracene, tetracene, and perhaps pentacene). An origin for these molecules in carbon dust is indicated and is consistent with the structure of laboratory hydrogenated amorphous carbons. Benzene and the simplest aromatic ring molecule, cyclopropenylidene, may be observable in sources which show the UIR emission features. 25 refs.
