| Popis: | Several vibronic bands associated with v′=0 and 1 for the C 3 Δ –X 3 Δ transition of TiO have been observed using a dispersed laser induced fluorescence (DLIF) technique. From intensity distributions of the present DLIF and previous emission spectra, the dependence of the electronic transition moment, Re(r), for the C 3 Δ –X 3 Δ system was determined as a function of the internuclear distance, r. For the determination of the absolute Re(r) function, the reported radiative lifetimes of v′=0 and 1 in the C 3 Δ state were included in the analysis; Re(r) was determined as Re(r)=1.3039(49)[1+22.1(28)(r−r0)2−150(25)(r−r0)3] (r0=1.65869 and 1.62093 A ⩽r⩽1.80255 A). The obtained values of Re(r) were simultaneously analyzed with those for the B 3 Π –X 3 Δ system, the hyperfine coupling constants for the X 3 Δ state, and the spin–orbit constants for the X 3 Δ , B 3 Π , and C 3 Δ states to assess the ionic and orbital characters. |
