This Perspective attempts to shed light on developments in the theoretical and experimental
study of molecular anions highlighting more recent workers in the field. The species I …

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 …

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

Bromo‐1‐(3, 3‐dinitroazetidin‐1‐yl) ethan‐1‐one (RRx‐001) is a hypoxic cell
chemotherapeutics with already demonstrated synergism in combined chemo‐radiation …

Electronic resonances commonly decay via internal conversion to vibrationally hot anions
and subsequent statistical electron emission. We observed vibrational structure in such an …

Feshbach resonances corresponding to metastable vibrational states of the dipole-bound
state (DBS) have been interrogated in real time for the first time. The state-specific …

Experimental characterization of the transition state poses a significant challenge due to its
fleeting nature. Negative ion photodetachment offers a unique tool for probing transition …

Conspectus Nonvalence bound states (NBS) are anionic states where the excess electron is
extremely loosely bound to the neutral core through long-range potentials. In contrast to the …

Non-valence states in neutral molecules (Rydberg states) have well-established roles and
importance in photochemistry, however, considerably less is known about the role of non …

Valence-bound anions with polar neutral cores (μ>∼ 2.5 D) can support dipole-bound
excited states below the detachment threshold. These dipole-bound states (DBSs) are …
