γ射线辐照TBP,TBP的激发单态分解导致形成不饱和TBP(脱氢TBP),其G_(双键)=1.01±0.1,H_2O与O_2的存在可抑制不饱和TBP的生成。TBP的第二种激发态(三重态)可导致形成TBP聚合体,O_2的存在可抑制TBP聚合体的形成,但使DBP的G值增大。
γ-ray irradiation induced the formation of unsaturated TBP (dehydrogenated TBP) by the excited singlet decomposition of TBP and TBP. The G_ (double bond) = 1.01 ± 0.1. The presence of H_2O and O_2 inhibited the formation of unsaturated TBP. The second excited state (triplet state) of TBP leads to the formation of TBP aggregates. The presence of O 2 inhibits the formation of TBP aggregates, but increases the G value of DBP.
