ABSTRACT: The transient
absorption spectra and kinetics of excited triplet state of anthraquinone
derivatives 2-anthraquinonesulfonatesodium (AQS) and 2-deoxythymidine (dT)
have been investigated in CH3CN-H2O (97:3) using the time-resolved
laser flash photolysis technique (KrF, 248 nm). The absorption spectra of dT
radical cation and the radical anion of AQS have been observed. From dynamic
and thermodyrnamic analysis, the mechanism of this transient reaction has
been initially analysed.
