Measurements of the rise and decay times, relative intensities, and pressure dependence of the 1.0, 1.9, and 2.3 ..mu..m laser-induced fluorescence (LIF) of plutonium hexafluoride (PuF/sub 6/) excited at 795 nm are reported. Einstein A-italic coefficients of the transitions are also determined. Then, all these quantities are used to determine many of the rate constants of the kinetics of energy flow and also the relative quantum yields into the low-lying electronically excited states of PuF/sub 6/. In addition, the data indicate that both radiating and nonradiating states are involved in the relaxation.
