This research aims to study the electronic relaxation dynamics of hydrated electrons in size-selected water clusters.
Time-resolved photoelectron imaging was utilized to observe the dynamics of hydrated electron clusters.
Excitation of excess electrons was achieved using ultrafast laser pulses, monitored through photodetachment and photoelectron imaging.
Clusters of varying sizes with n ranging from 25 to 50 were examined.
The lifetimes for (H2O)n- clusters ranged from 180 to 130 femtoseconds, decreasing with increased cluster size.
For (D2O)n- clusters, lifetimes were observed from 400 to 225 femtoseconds, also decreasing with size.
Results supporting the nonadiabatic relaxation mechanism indicate an internal conversion lifetime of 50 femtoseconds for the bulk hydrated electron.

Bragg et al. (2004) studied this question.
