Unidentified infrared spectral features
Abstract
It is noted that the infrared spectra between 2 and 13 microns of a variety of objects have become available in the past few years. Attention is given to the fact that these spectra have shown many objects to have up to six emission features that are still unidentified. It is reported that other objects show absorptions due to ice, carbon monoxide, silicates, and two unidentified features. Discussion covers the observational characteristics of the unidentified features together with possible identifications.
