Glassgold, A.E., and W.D. Langer, 1976: Abundances of simple oxygen-bearing molecules and ions in interstellar clouds. Astrophys. J., 206, 85-99, doi:10.1086/154358.

The abundances of simple oxygen-bearing interstellar molecules in warm (T ≳ 40 K), diffuse, and moderately thick clouds are calculated on the basis of binary gas-phase reactions. The most important reactions are ion-molecule, charge-exchange, and dissociative-recombination reactions, as suggested mainly by earlier workers. The progenitor of these molecules in diffuse clouds is the cosmic-ray-produced H+ ion, working through the charge-exchange reaction with O. The ionization of H+ and He+ is also discussed. Dissociative charge exchange of He+ with H2 is an important source of H+ in regions of large fractional abundance of H2, as well as an important destruction mechanism for He+ even for small f (≳ 0.1). The calculated molecular abundances are consistent with some of the available observational information.
