The Electronic Transition Moment Function for the B3Π–X3Δ System of TiO

The electronic transition moment function for the system of TiO

“…In a way identical to the previous analysis of the B 3 P-X 3 D transition [7], the relative DLIF intensity of the ðv 0 ; J 0 Þ ! ðv 00 ; J 00 Þ transition is represented as…”

“…The detailed description of the DLIF equipment can be found in our previous papers [7,24]. TiO was produced in a microwave discharge (2.45 GHz, 80 W) through a flowing mixture of Ar and traces of TiCl 4 vapor and O 2 .…”

“…Here the semi-empirical model is modified to analyze the present, absolute R e ðrÞ function for the C 3 D-X 3 D transition. This analysis includes also the R e ðrÞ function for the B 3 P-X 3 D transition [7] and the fine and hyperfine parameters for the X 3 D [20,21], B 3 P [22,23], and C 3 D [15] states to gain the detailed information on the electronic structures.…”

“…In many studies, s v 0 J 0 was analyzed on the assumption that R e ðrÞ is independent of r. As a consequence, a global analysis of the above information can provide the absolute function. Recently, we demonstrated that R e ðrÞ for the B 3 P-X 3 D transition of TiO was determined as a precise function of r by the global fit of three datasets [7].…”

“…The global analysis of the present and previous [14] distributions and the radiative lifetimes [11] was made from which the absolute R e ðrÞ function was precisely determined. The derived values of R e ðrÞ were combined with those for the B 3 P-X 3 D transition [7], the hyperfine coupling constants of the X 3 D state [20], and the spinorbit coupling constants of the X 3 D [21], B 3 P [22,23], and C 3 D [15] states to discuss the orbital nature of the unpaired electrons.…”
