Bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato) dioxo uranium (VI) is stable and volatile at ≈120°C, particularly with a ligand such as ammonia or trimethyl phosphate, and susceptible to multiphoton dissociation (mpd) via tle uranyl asymmetric vibration at ≈950 cm−1. There are two dissociation paths: (i) detachment of the ligand at fluences below 0.2 J cm−2; (ii) permanent dissociation Of UO2(hfacac)2into UO2F2and a furanone C5F5O2H at fluences above 0.6 J cm−2. Ligand detachment appears to be a conventional unimolecular mpd reaction describable by master equations in spite of the remarkably low fluence threshold. Permanent dissociation shows much greater chemical complexity. |
