摘要：

A transient species has been observed in the ultraviolet flash photolysis of uracil in aqueous solution which is quenchable by O2 and by uracil itself, but not by N2O. This transient has a mean lifetime of 6.1 ± 0.5 μsec in the absence of quenching and an absorption spectrum which peaks at 380 nm. Analysis of the kinetics of quenching shows this transient to be the triplet state which is the direct precursor of the uracil dimer photoproduct. © 1969.
