Abstract (from CDS):

We have mapped the 13 CO (1-0) line in a region of sky towards the star Cyg OB2 No. 12. The observations rule out the possibility that the molecular material along the line of sight is distributed over a long path of very dilute gas. Instead, we present unambiguous evidence of well-defined kinematical structures, which might be assembled to form a cloud complex. The chemistry that leads to H+3appears decoupled from that responsible for the production of heavier species.
