Several vibronic bands associated with v′=0 and 1 for the 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 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 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 system, the hyperfine coupling constants for the state, and the spin–orbit constants for the , , and states to assess the ionic and orbital characters. |
