英文摘要The laser-induced fluorescence (LIF) excitation spectra of WO molecule have been recorded in the energy range of 18,900-23,500 cm(-1) using laser ablation of tungsten target and reaction with free jet expansion of oxygen. Totally 63 vibronic transition bands were observed, and 60 bands were grouped into 10 electronic transition progressions, where 8 electronic transition progressions have the X0(+) state as the lower state, as well as 2 progressions have the X1 state as the lower state. The electronic transition systems [21.5]0(+)-X0(+) and [23.3]1-X0(+) were newly identified by LIF spectroscopy. The molecular constants, including rotational constant, vibrational frequency, vibrational anharmonic constant, in the electronic excited states were obtained through rotational analysis of the spectra. In addition, the fluorescence lifetimes of the vibronic states were measured under the collision-free condition by exponentially fitting the fluorescence decay. (C) 2019 Elsevier Inc.
