摘要 Based on previous laser-induced fluorescence excitation spectroscopy work, the vibrational constants of neutral FeS in the X5 △ electronic state were obtained by directly mapping the ground-state vibrational levels up to v"=3 using conventional laser-induced dispersed fluorescence spectroscopy. The vibrational frequency of FeS(X5 △) (518±5 cm-1) agrees well with that reported in a recent PES measurement (520±30 cm-1) [J. Phys. Chem. A 107, 2821 (2003)] which is the only one prior experimental vibrational frequency value for the 5 △ state of FeS. Careful comparisons of our experimental results and those documented in the literature (mainly from theoretical predictions) suggest that the ground state of FeS is 5 △ state.
