| Abstract: | The argument for the similarity of the composition of cometary volatiles to that of interstellar molecules has been strengthened by the analysis of CO+ and CO2+ emission of the comet West. The strong 6300 Å emission of oxygen atoms can be interpreted in terms of photodissociation of OH by the solar Lyman-alpha radiation, and not as being due to photo-dissociation of CO2 of speculatively large amount. |
