Over the last few decades, conical intersections (CoIns) have grown from theoretical
curiosities into common mechanistic features of photochemical reactions, whose function is …

Time-resolved photoelectron spectroscopy (TRPES) has become one of the most
widespread techniques for probing nonadiabatic dynamics in the excited electronic states of …

The electronic character of photoexcited molecules can abruptly change at avoided
crossings and conical intersections. Here, we report direct mapping of the coupled interplay …

Recent developments in X-ray free-electron lasers have enabled a novel site-selective
probe of coupled nuclear and electronic dynamics in photoexcited molecules, time-resolved …

The excited state non-adiabatic dynamics of the smallest polyene, trans 1, 3-butadiene (BD),
has long been the subject of controversy due to its strong coupling, ultrafast time scales and …

We present the first vacuum ultraviolet time-resolved photoelectron spectroscopy (VUV-
TRPES) study of photoisomerization dynamics in the paradigmatic molecule cis-stilbene. A …

The photochemistry of cis-stilbene proceeds through two pathways: cis-trans isomerization
and ring closure to 4a, 4b-dihydrophenanthrene (DHP). Despite serving for many decades …

Time-resolved photoelectron imaging (TRPEI) is a highly differential technique for the
detailed study of non-adiabatic energy redistribution dynamics operating in the electronically …

We present an extension of the combined density functional theory (DFT) and multireference
configuration interaction (MRCI) method (DFT/MRCI)[S. Grimme and M. Waletzke, J. Chem …

Summary The S 1 (2 1 A g–) state is an optically dark state of natural and synthetic pi-
conjugated materials that plays a role in optoelectronic processes, such as energy …
