Abstract: | The pure rotational spectrum of 13C2HD was recorded in the range 100–700 GHz. Lines belonging to the ground vibrational state were observed from J″ = 1 to J″ = 11. Several absorption lines were also detected in the bending states v4 = 1 (Π), v5 = 1 (Π), v4 = 2 (Σ+ and Δ), v5 = 2 (Σ+ and Δ), v4 = v5 = 1 (Σ?, Σ+ and Δ), v4 = 3 (Π and Φ) and v5 = 3 (Π and Φ). The transition frequencies measured in this work were fitted together with all the infrared lines available in the literature. The global fit allowed a very accurate determination of the vibrational, rotational and ?-type interaction parameters for the bending states of this molecule. |
