Interpretation of the carbon recombination line,citing star may be, but should not be assumed to be, the source of the photons which ionize carbon in the region giving rise to the observed recombination lines. The origins of the narrow hydrogen and heavier element lines are also discussed.

Recent interstellar molecular line work,ve an . limit to the abundance ratio .C/.C of 36 ± 5. A short discussion of the interstellar chemistry leads to the conclusion that hydrocarbons such as acetylene, HCCH, ethylen, H.CCH. and ethane H.CCH. should be present in interstellar clouds.

https://doi.org/10.1007/978-3-662-41023-3The theory of formation of various molecules, both on surfaces of interstellar dust-grains and in gas-phase reactions, is reviewed. Destruction of molecules, the special problems of very dark clouds and the life-history of dust-grains are also reviewed briefly.

Statik flüssiger und gasförmiger KörperThis report deals with radio observations of the carbon and narrow hydrogen recombination lines. The theoretical discussion of these data are contained in the paper by Walmsley, in this volume.
