Abstract
The rotational transition measurements of DCO+ in bending-excited states were extended to satellites with higher values of the vibrational angular momentum quantum number, ℓ. A detailed scheme of the energy levels within the ℓ manifolds was derived. The equilibrium rotational constants for all the isotopomers of the formyl ion were derived by means of a proper combination of the perturbed effective rotational constants to compensate for the Coriolis contributions. In this way, an accurate equilibrium structure was obtained.File in questo prodotto:
