Scientific paper

In light of new laboratory measurements and theoretical techniques, previously suggested gas phase syntheses of dimethyl ether (CH3OCH3), ethyl alcohol (C2H5OH), and acetaldehyde (CH3CHO) in dense interstellar clouds have been reexamined. Several radiative association rate coefficients leading to the precursor ions to these species are now calculated to be significantly smaller than previous estimates. On the other hand, a new and rapid synthesis of the precursor ion to acetaldehyde appears to be viable. The diminution in the values of selected radiative association rate coefficients raises the possibility that normal gas phase syntheses under ambient dense cloud conditions may not account fully for the observed abundances of ethyl alcohol and, especially, dimethyl ether.
