Abstract
The kinetics of the two-photon ionization (TPI) of N, N, N', N'-tetramethyl benzidine (TMB) in CH2Cl2-doped solid argon using 313 nm Hg lamp radiation is investigated by means of ultraviolet/visible (UV/VIS) absorption spectro scopy. The experimental findings can be quantitatively understood on the ba sis of a rate equation model. The ionization cross-section of TMB in the lo west triplet state and the rate constant of cation-electron recombination a re obtained by adapting calculated to measured irradiation time-dependent c oncentrations of the cation.
