ORGANIC MOLECULES IN SPACE PREDICTED. “Identification of the λ2, 200Å interstellar absorption feature (1977), by F. Hoyle & C. Wickramasinghe. “Here we identify this band as representing the integrated effect of a set of bicyclic compounds, each with the empirical formula C8H6N2. Such nitrogenated structures could form in stellar mass flows of the type which we have also discussed. A significant mass fraction of all interstellar material might exist in this form.”
