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 …

Photoactive proteins that efficiently and selectively transfer light energy into a physical
response are ubiquitous in nature. The small molecule chromophores that lie at the heart of …

Controlling excited-state reactivity is a long-standing challenge in photochemistry, as a
desired pathway may be inaccessible or compete with other unwanted channels. An …

Phenolate photooxidation is integral to a range of biological processes, yet the mechanism
of electron ejection has been disputed. Here, we combine femtosecond transient absorption …

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

Ab initio electron-propagator calculations continue to be useful companions to experimental
investigations of electronic structure in molecular anions. A new generation of electron …

Frequency-resolved (2D) photoelectron (PE) spectra of the anionic clusters (C6F6) n–, for n=
1–5, and time-resolved PE spectra of I–C6F6 are presented using a newly built instrument …

Photodissociation action spectroscopy has made a great progress in expanding
investigations of gas‐phase ion structures. This review deals with aspects of gas‐phase ion …

Analytical nuclear gradient and derivative coupling theories for the quasidegenerate N-
electron valence state perturbation theory using state-averaged orbitals and density …

We present the spectrum of the S1← S0 transition of an anionic model for the chromophore
of the green fluorescent protein in vacuo at cryogenic temperatures, showing previously …
