Gas-phase anions present an ideal playground for the exploration of excited-state dynamics.
They offer control in terms of the mass, extent of solvation, internal temperature, and …

The role of extended seams of conical intersection in excited‐state mechanisms is reviewed.
Seams are crossings of the potential energy surface in many dimensions where the decay …

When high-energy radiation passes through aqueous material, low-energy electrons are
produced which cause DNA damage. Electronic states of anionic nucleobases have been …

Even though there is a critical dipole moment required to support a dipole-bound state
(DBS), how molecular polarizability may influence the formation of DBSs is not well …

We summarize how gas-phase ultrafast charged-particle spectroscopy has been used to
provide an understanding of the photophysics of DNA building blocks. We focus on adenine …

The recently developed method of frequency-, angle-, and time-resolved photoelectron
imaging (FAT-PI) applied to the study of the dynamics of resonances of open-shell anions is …

Nonvalence states of neutral molecules (Rydberg states) play important roles in
nonadiabatic dynamics of excited states. In anions, such nonadiabatic transitions between …

The reaction of low-energy electrons with neutral molecules to form anions plays an
important role in chemistry, being involved in, for example, various biological and …

The resonant attachment of a free electron to a closed shell neutral molecule and the
interplay between the following electron detachment and electronic relaxation channels …

A combined frequency-, angle-, and time-resolved photoelectron spectroscopy study is used
to unravel the excited state dynamics following UV excitation of the isolated anionic …
