Abstract
The laser-induced fluorescence (LIF) spectrum of jet-cooled CoF has been obtained in the wavelength region of 260-290 nm for the first time. Seventeen vibronic bands were observed and assigned to three types of transition from the ground state to upper states Ωâ²Â = 3, 4, 5 by rotational analysis. A new vibrational transition with the 0-0 band at 34697.22 cmâ1 has been assigned as the [34.7]3Î5-X3Φ4 transition and effective equilibrium molecular constants for the upper state have been determined. In addition, lifetime measurements have been carried out for most of the bands under collision-free conditions. On the basis of the spectroscopic data and lifetime measurements, the electronic structures of these possible high-lying electronic states are discussed.
