We report the first detection of the radical C/sub 3/N in interstellar sources, at the centers of the two dark clouds TMC 1 and TMC 2. The very small line widths observed for this low-order transition (N=3..-->..2) allow a partial resolution of the hyperfine structure and a tentative estimate of this radical's hyperfine constants. The C/sub 3/N/HC/sub 3/N abundance ratio observed in the two clouds is similar to that in IRC+10216, but much larger than the upper limit derived for Orion A and Sagittarius B2.
