Laser-induced Fluorescence Spectroscopy of Uranium Monofluoride
文献摘要：
The laser-induced fluorescence excita-tion spectra of ura-nium monofluoride have been recorded in the range of 17000-19000 cm-1 using two-dimensional spec-troscopy.High resolution dispersed fluorescence spectra and time-resolved fluorescence spectroscopy were also recorded.Three rotationally resolved bands were intensively analyzed,and all bands were found to be derived from the ground state X(1)4.5 with a rotational constant of 0.23421 cm-1.The low-lying electronic states were observed near 435 and 651 cm-1 in the dispersed fluorescence spectra,which were assigned as Ω'=3.5 and 2.5,respectively.The vibrational constants for the X(1)4.5 and X(1)3.5 states were calculated.The branching ratios of the dispersed fluorescence spectra for the[18.62]3.5,[17.72]4.5,and[17.65]4.5 states were reported.Radiative lifetime of 332(9)ns,825(49)ns,and 433(15)ns for the[18.62]3.5,[17.72]4.5,and[17.65]4.5 states were obtained by fitting the time-resolved fluorescence spectroscopy,respectively.Transition dipole moments were performed using the branching ratios and the radiative lifetimes.
