This review describes how conical intersections affect measured molecular spectra and
simple photofragmentation processes. We consider excitations that result in electron …

A detailed understanding of the properties of electronic excited states and the reaction
mechanisms that molecules undergo after light irradiation is a fundamental ingredient for …

Evolution has ensured that plants and animals have developed effective protection
mechanisms against the potentially harmful effects of incident ultraviolet radiation (UVR) …

Biochemical reactions are subject to the particular environmental conditions of planet earth,
including solar irradiation. How DNA responds to radiation is relevant to human health …

Photodegradation characteristics of pharmaceuticals and personal care products (PPCPs)
during UV irradiation are of practical and scientific importance in selecting operational …

Using recently developed full-dimensional coupled quasi-diabatic ab initio potential energy
surfaces including four electronic (1ππ, 1ππ*, 11πσ*, and 21πσ*) states, the tunneling …

This Perspective addresses the use of coupled diabatic potential energy surfaces (PESs)
together with rigorous quantum dynamics in full or reduced dimensional coordinate spaces …

Abstract The Multiconfigurational Ehrenfest (MCE) method is a quantum dynamics technique
which allows treatment of a large number of quantum nuclear degrees of freedom. This …

Directly imaging structural dynamics involving hydrogen atoms by ultrafast diffraction
methods is complicated by their low scattering cross sections. Here we demonstrate that …

In an effort to illuminate why nature has chosen a particular set of bio-molecular 'building-
blocks' for life, recent years have seen an up-surge of gas-phase spectroscopy experiments …
