Picosecond Pulse Radiolysis Study on the Radiation-Induced Reactions in Neat Tributyl Phosphate

Abstract: The ultrafast radiolytic behavior of tributyl phosphate, TBP, has been investigated using 7 ps electron pulses with 7 MeV kinetic energy, from which two key species have been observed and characterized: the TBP solvated electron (e) and the TBP triplet excited state TBP* (a) or its fragmentation products. The e exhibits a broad absorption band in the visible and near-infrared (NIR) spectrum, with a maximum beyond our 1500 nm detection limit. Nitromethane was used to scavenge e to confirm its absorption spectru… Show more

“…Experimental methods such as gas chromatography or mass spectrometry permit the identification of degradation products resulting from the passage of ionizing radiation in matter. Pulsed irradiation experiments have made it possible to trace the chronology of these mechanisms, both intra- and inter-molecular, down to the picosecond scale , in real-time. There is also work studying indirect irradiation by secondary electrons emitted with the medium .…”

“…8 Mostafavi et al employed picosecond pulse radiolysis to probe the TBP solvated electron ( e TBP − ), the TBP triplet excited state, and radical cations. 9 A number of works were also devoted to the analysis of TBP neutral radicals under the action of X-rays and γ-rays. 8,10,11 The irradiation at a low temperature (77 K) made it possible to detect alkyl-type radicals with a radiation-chemical yield of 1.34 μmol J −1 (12.9 radicals/100 eV) 10 or 0.71 μmol J −1 (6.8 radicals/100 eV).…”
