چکیده انگلیسی
The electronic spectra of the titanium monohalides, TiCl and TiBr, have been investigated in the blue-violet region using a laser ablation molecular beam spectrometer. Five subbands assigned as 4Î5/2-X4Φ3/2 (0, 0), 4Î5/2-X4Φ3/2 (1, 1), 4Î5/2-X4Φ5/2 (0, 0), 4Î7/2-X4Φ5/2 (0, 0) and 4Î7/2-X4Φ7/2 (0, 0) were observed and recorded at both low and high-resolution for titanium monochloride. A Hund's case (a) rotational analysis has been carried out for the 48Ti37Cl and 48Ti35Cl isotopic species, and polynomial analyses for these, as well as the 46Ti35Cl, 47Ti35Cl, 49Ti35Cl, and 50Ti35Cl isotopologues have been completed. The same spectral region yielded several molecular transitions for titanium monobromide, 10 of which were recorded at high resolution. Six of these have been attributed to a 4Î-X4Φ electronic transition at 23 484 cmâ1, while the remaining four have been assigned to a second 4Î-X4Φ electronic transition at 23 613 cmâ1. A Hund's case (a) global analysis has been carried out for the 48Ti79Br and 48Ti81Br isotopologues.
