The CH distribution in the galactic plane has been determined through observations of the ground state main line transition 2π1/2, J=1/2, F=1-1 at 3335 MHz. The longitude ranges 10°≤ℓ≤60° and 60°<ℓ≤230 have been covered with the spacings 2°.5 and 5°, respectively. The derived radial distribution is similar to that of CO, although differencies may exist. From observations at ℓ=30° and 43°.26 the CH layer halfwidth is estimated to be 50 pc, in close agreement with that of CO. A CH displacement below the standard plane is observed in these directions.
