Deuterium Enrichment of Interstellar Methanol Explained by Atom Tunneling

We calculate, down to low temperature and for different isotopes, the reaction rate constants for the hydrogen abstraction reaction H + H3COH → H2 + CH2OH/CH3O. These explain the known abundances of deuterated forms of methanol in interstellar clouds, where CH2DOH can be almost as abundant as CH3OH....
