Scientific paper

An attractively simple scheme by which molecules having long carbon chains are formed in interstellar clouds through the radiative association family Cn+C+→Cn+1++hν is examined. It is rejected as probably being much too inefficient. Other schemes involve the synthesis of a big molecule in a single step, as for example NH3+CH3+→NH3×CH3++hv on which related flow-tube experiments have been performed. If a competing exothermic channel exists, it will in general severely suppress the radiative association rate coefficient.
