Isotope Fractionation in Interstellar Moleculesal electron density and CO abundance — can be derived from the fractionation process producing the enhanced DCO./HCO. ratio. Possible fractionation reactions for isotopes of other elements (oxygen, sulfur) are mentioned briefly.

https://doi.org/10.1007/978-3-662-52815-0Mahoney, McCutcheon and Shuter (1976) reported observations of the J = 1 → 0 transition of three isotopes of CO in the dust cloud Lynds 134 using the 4.6 m telescope at Aerospace Corporation. Here we discuss a new observation of .C.O and consider further the question of the ratio .C.O/.C.O across the dust cloud.
