Ultrafast processes in light-absorbing proteins have been implicated in the primary step in
the light-to-energy conversion and the initialization of photoresponsive biological functions …

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

Vitamin A (all-trans-retinol, 1, Figure 1) is considered the most multifunctional vitamin in the
human body. 1 It plays key roles in many physiological processes such as vision …

As the year-to-year gains in speeds of classical computers continue to taper off,
computational chemists are increasingly examining quantum computing as a possible route …

The retinal protonated Schiff-base (RPSB) in its all-trans form is found in bacterial
rhodopsins, whereas visual rhodopsin proteins host 11-cis RPSB. In both cases …

Schizorhodopsin (SzR) is a newly discovered microbial rhodopsin subfamily, functioning as
an unusual inward-proton (H+) pump upon absorbing light. Two major protein structural …

Conical intersections are molecular configurations at which adiabatic potential-energy
surfaces touch. They are predicted to be ubiquitous, yet condensed-phase experiments …

Sequential two-photon excitation increases the cycloreversion yield of a diarylethene-type
photochromic molecular switch compared with one-photon excitation. This letter shows for …

Comparative modeling and ab initio multiconfigurational quantum chemistry are combined
to investigate the reactivity of the human nonvisual photoreceptor melanopsin. It is found that …

In photoinduced molecular reaction dynamics, the effects of electronic charge redistribution
can lead to multiple pathways that are determined by the nature of the initial structures …
