A single mode cw dye laser excitation along with velocity modulation detection was used to record between 17 100 and 18 600 cm−1 the absorption spectrum of the Δ(3d4s)–X33Φ(3d2) visible system of TiCl+ produced in an ac ...

The rotational structure of the (0,0) and (1,0) vibrational bands has been observed and fully analyzed for the main isotopomer Ti35Cl+ as well as for Ti37Cl+. Beside the confirmation of the nature of the two electronic states, the observation of the forbidden Δ23–3Φ2 and Δ33–3Φ3 intercombination transitions allowed the first experimental determination of the spin–orbit constants and a detailed characterization of both the Δ3 and Φ3 states through a matricial fitting of the data. Molecular parameters have been derived.Show less >
