The laser-induced ﬂuorescence excitation spectra of UF have been recorded in the range of 17000−19000 cm-1 using two-dimensional spectroscopy. High resolution dispersed ﬂuorescence spectra and fluorescence decay curves time-resolved fluorescence spectroscopy were also recorded. Three rotationally resolved bands have been 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 have been observed near 435 and 651 cm-1 in the dispersed fluorescence spectra, which were assigned as Ωʹ = 3.5, and 2.5, respectively. The vibrational constants for the X(1)4.5 and X(1)3.5 states have been 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 lifetimes of 332(9), 825(49), 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 fluorescence decay curves time-resolved fluorescence spectroscopy, respectively. Transition dipole moments were performed using the branching ratios and the radiative lifetimes.
