“…Dieber and Kay assigned the ground state as 4 Σ - (σδ 2 ) and interpreted the spectroscopic feature at 3.04 eV as due to the 4 Π−X 4 Σ - transition. This was questioned by Shenyavskaya and Dubov, who performed a rotational analysis on the 0−0 and 1−0 bands and reassigned the ground state as 2 Δ (σ 2 δ). Recently, Ram et al observed a 4 Φ− 4 Φ transition, using Fourier transform emission and laser excitation spectroscopy, and assigned the ground state as X 4 Φ (σπδ).…”

“…Later Chatalic et al [13] recorded the electronic emission spectrum and tentatively identified a 4 G-4 R À transition in the 407 nm region based on comparisons with TiCl. In 1985, Shenyavskaya and Dubov [14] photographed the emission spectrum in the region of 300-700 nm which led to questions about the 4 G-4 R À assignments. Some bands previously assigned to 4 G-4 R À transition were rotationally analyzed and reassigned as 2 U-2 D and 2 D-2 D transitions.…”

a b s t r a c tThe laser-induced fluorescence (LIF) spectrum of jet-cooled 48 TiF has been obtained in the wavelength region of 245-270 nm for the first time. Six pairs of vibronic bands were observed and assigned to two new transitions [37.8] 4 U-X 4 U and 4 D-X 4 U. Rotational analysis was carried out for the (m 0 = 0-3 to m 00 = 0) vibrational bands of the [37.8] 4 U 3/2 -X 4 U 3/2 and [37.8] 4 U 5/2 -X 4 U 5/2 subbands, and also, the (m 0 , 0) and (m 0 +1, 0) vibrational bands of the 4 D 1/2 -X 4 U 3/2 and 4 D 3/2-X 4 U 5/2 subbands. The effective equilibrium molecular constants for the [37.8] 4 U 3/2 and [37.8] 4 U 3/2 upper states were determined. In addition, lifetime measurements were carried out for all of the observed bands under collision-free conditions. On the basis of the spectroscopic constants and lifetime measurements, the electronic transitions involved in the observed high-lying electronic states are discussed.

“…The most prominent group of the bands in the 407 nm region presented in [1,2] was vibrationally analyzed and assigned as belonging to a 4 P-X 4 R transition. These bands were then rotationally analyzed by Shenyavskaya and Dubov [3], who reassigned them to a 2 U-2 D transition on the basis of the appearance of the rotational structure and theoretical results [4] which predicted close-lying, low-energy states, 4 R À and 2 D either of which could be expected to be the ground state.…”
