Electron medium dynamics controlled

Experiments aimed at probing solvent dynamical effects in electrochemical kinetics, as in homogeneous electron transfer, are only of very recent origin, fueled in part by a renaissance of theoretical activity in condensed-phase reaction dynamics [47] (Sect. 3.3.1). It has been noted that solvent-dependent rate constants can sometimes be correlated with the medium viscosity, t] [101]. While such behavior may also signal the onset of diffusion-rather than electron-transfer control, if the latter circumstances prevail this finding suggests that the frequency factor is controlled by solvent dynamics since td and hence rL [eqn. (23), Sect. 3.3.1] is often roughly proportional to... 

As an analysis of this laser control of chemical reaction in terms of electron dynamics, in Figs. 8.5 and 8.6 we present the snapshots of electron current flux and corresponding time derivative of electron density at the time 15 and 25 fs for the cases with the pulse width = 4.84 fs starting from the asymptotic ground (Na+Cl) and first excited (Na+- -Cl ) states. Due to the non-resonance for electronic transition as well as medium strength of the laser field, complicated interference patterns are found in the spatial distribution of the flux and in the time derivative of electron density.
