The initial charge distributions, which were recognized as very important, were analyzed in more detail in a number of works [32]. The analysis was extended to multichannel ionization [179], and the role of the excitation lifetime was specified [25]. A few articles devoted to them were published by Murata and Tachiya [26,27]. Earlier these authors studied experimentally the non-stationary kinetics of fluorescence quenching, which was fitted numerically...

The effect is significant for reactions with short half-times. In an ordinary diffusion-limited reaction under conditions where the species B is in great excess, the half-time is l/(/ diff[B]). If / diff 10 ° sec-, a steady-state treatment of the kinetics will suffice as long as [B] < 0.1 If [B] is larger, the effect of transient behavior cannot be ignored. Another instance where transients are important is in the kinetics of fluorescence quenching. Here, the intrinsic lifetimes of the photoexcited species are typically 10 sec. The photostationary state is not established and effects attributable to the time dependence of fcapp can be observed.
