The laser-induced fluorescence excitation spectrum of jet-cooled CoF molecules has been studied in the range of 18 800–22 000 cm−1. Ten observed vibronic bands have been classified into three transitions with the 0–0 band at 18 909, 19 236, and 20 654 cm−1, assigned as the [18.8]3Φ4–X3Φ4, [19.2]3Φ4–X3Φ4, and [20.6]3Γ5–X3Φ4 transition, respectively, the two 3Φ states, [18.8]3Φ and [19.2]3Φ, are consistent with Adam’s results (10). The previously unanalyzed [20.6] state is identified in the current work. A rotational analysis of [20.6]3Γ5–X3Φ4 transition has been performed and effective equilibrium molecular constants have been determined for the first time. In addition, lifetime measurements of the three electronic transitions were carried out under the collision-free condition. From the lifetime analysis, we consider that the V=1, 2, and 3 vibrational levels of [18.8]3Φ state are perturbed by another state.
