Langer, W.D., 1977: Isotopic abundance of CO in interstellar clouds. Astrophys. J., 212, L39-L42, doi:10.1086/182370.

The fractional abundances of the isotopic species of carbon monoxide in interstellar clouds are calculated on a basis of gas-phase ion-molecule reactions. The 13CO/12CO ratio varies significantly with extinction of the ultraviolet radiation field, and in the outer regions of dark dense clouds 13CO may be enhanced by a factor of 10. The observational interpretation of the CO to H2 or AV relation and the isotopic abundances of carbon are complicated by these effects.
