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, R e (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 R e (r) function, the reported radiative lifetimes of v ' =0 and 1 in the C 3 Δ state were included in the analysis; R e (r) was determined as R e (r)=1.3039(49)[1+22.1(28)(r-r 0 ) 2 -150(25)(r-r 0 ) 3 ] (r 0 =1.65869 and 1.62093A=<r=<1.80255A). The obtained values of R e (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.
