- Abstract
The origin of the so-called "21 œm" feature that is especially prominent in the spectra of some carbon-rich protoplanetary nebulae is the matter of a lively debate. A large number of potential band carriers have been presented and discarded within the past decade. We present some of the problems related to the hitherto proposed feature identifications.
