Dynamics of cluster anions: A detailed look at condensed-phase interactions

This Perspective reflects on several recent advances in the studies of structure and dynamics of cluster anions, bridging the gap between 'cluster' and condensed phases. Applications involving photofragment and photodetachment spectroscopy, as well as femtosecond time-resolved experiments, are described. Special emphasis is given to the effects of microscopic solvation on the electronic structure and reactivity of negative ions in heterogeneous and homogeneous cluster environments. Some recent breakthroughs in experimental methodology are also outlined, in particular the application of photofragment and photoelectron methods and the imaging technique to the studies of molecular cluster anions.
