✦ Synopsis

New measurements have been carried out in the rotational spectrum of C 2 H / 3 using a negative glow discharge. An improved experimental resolution made it possible to observe the small splitting due to the large-amplitude proton migration motion for a larger number of lines than in previous studies. These new measurements along with existing ones were analyzed using an internal-axis-method-like approach which allowed us to reproduce the observed splittings within the experimental resolution. This theoretical approach provided us with crucial information on the proton trajectories along the tunneling path.
