Abstract
A spectroscopic identification of the infrared continuum radiation is proposed for the planetary nebula NGC 7027. Hydrogenated amorphous carbon (α:C-H) is shown to account for the undulating spectrum between 5 and 15μm. The unidentified infrared emission bands lie at the peaks in the α:C-H spectrum, pointing to their association with a carbon polymorph, possibly α:C-H or polycyclic aromatic hydrocarbon molecules (PAHs). Except for atomic emission lines, all the infrared emission from NGC 7027 comes from one or another polymorph of carbon.
