Understanding the properties of electronically excited states is a challenging task that
becomes increasingly important for numerous applications in chemistry, molecular physics …

Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

Organisms of all domains of life use photoreceptor proteins to sense and respond to light.
The light-sensitivity of photoreceptor proteins arises from bound chromophores such as …

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 …

We review state-of-the-art electronic structure methods based both on wave function theory
(WFT) and density functional theory (DFT). Strengths and limitations of both the wave …

Ever since the conversion of the 11-cis retinal chromophore to its all-trans form in rhodopsin
was identified as the primary photochemical event in vision, experimentalists and …

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

The first book dedicated to this new and powerful computational method begins with a
comprehensive description of MCTDH and its theoretical background. There then follows a …

▪ Abstract Nonadiabatic effects play an important role in many areas of physics and
chemistry. The coupling between electrons and nuclei may, for example, lead to the …

There is a clear need for computationally inexpensive electronic structure theory methods
which can model excited state potential energy surfaces. Time-dependent density functional …
