The detection of the (C-13)O J = 3-2 line is reported, and a 15-arcsec-resolution, seven-point map of the (C-12)O J = 3-2 line in IC 342 is presented. The (C-13)O line strength, when compared to the lower-J line strengths at similar spatial resolution, suggests that the (C-13)O lines are optically thick in the inner 200 pc of IC 342. The physical conditions in the molecular gas in the inner region of IC 342 are similar to the conditions in the inner 200 pc of the Galaxy. 38 refs.
