Guelin, M., W.D. Langer, R.L. Snell, and H.A. Wootten, 1977: Observations of DCO+: The electron abundance in dark clouds. Astrophys. J., 217, L165-L168, doi:10.1086/182562.
The J = 2-1 rotational line of DCO+ has been definitely detected in five molecular clouds, including three dark clouds, L63, L134, and L134 N, and marginally detected in four others. The DCO+ emission has been mapped in L134 N and extends over a region of 3'. The DCO+/HCO+ abundance ratio found at the centers of dark clouds is large and implies a fractional electron abundance of less than one hundred millionth. This low electron density sets constraints on the metals and possibly CO as well as on the hydrogen density.
