10 to 10 seconds prior to its trapping and possible solvation in a liquid will experience a sequence of events governed by the nature of the dynamical structure of the host liquid (Kenney-Wallace, 1981). Or to put the case in a macroscopic way a transient current in xenon is quite 

In recent papers the unresolved general Issues were outlined as follows (Kenney-Wallace et al., 1988a, 1987). 

Once again, in raising the profile of the simplest anion in nature in principle, these data focus our attention on one of the most intriguing quantum species in practice, for which a fully quantitative and predictive quantum theory has yet to be developed. Recent molecular dynamics simulations (Nichols and Chandler, 1986 Wallquist et al., 1986 Schnitker et al., 1986, 1987, 1988 Sprik et al., 1985, 1988 Jonah et al., 1986, Parrinello and Rahman, 1984) are now exploring various aspects of electron-cluster interactions to determine the cluster size, stability and structure of hydrated electrons in particular. In the chapter following this, we outline some of our initial attempts to introduce 

Within that issue the priority must be given to the key questions which we have posed (Kenney-Wallace and Jonah, 1982). First, how does the electronic motion couple into the fluctuating dynamical structure of the fluid, and second, how do the intermolecular forces and intrinsic motion of the atomic or molecular liquid respond to the sudden perturbation represented by an intense, transient field of a bare electron It is the second question which was the driving force in focusing our attention on nonlinear optical responses of liquids, via nonlinear laser spectroscopy at femtosecond timescales.
