Quantum chemistry meets one of its greatest challenges in the field of transition-metal compounds capable of fascinating chemical transformations. Complicated electronic …
We analyze the effect of removing self-interaction error on magnetic exchange couplings using the Fermi-Löwdin orbital self-interaction correction (FLOSIC) method in the framework …
In this work, we demonstrate that there is a continuum of different formulations for the decomposition of⟨ Ŝ 2⟩ that fulfills all physical requirements imposed to date. We …

The H2-evolving potential of [FeFe] hydrogenases is severely limited by the oxygen sensitivity of this class of enzymes. Recent experimental studies on hydrogenase from C …
The chemical bond is an important local concept to understand chemical compounds and processes. Unfortunately, like most local concepts, the chemical bond and the bond order do …

Heisenberg exchange spin coupling between metal centers is essential for describing and understanding the electronic structure of many molecular catalysts, metalloenzymes, and …
Hydrogenases comprise a variety of enzymes that catalyze the reversible oxidation of molecular hydrogen. Out of this group,[FeFe]-hydrogenase shows the highest activity for …
Many but not all iron–sulphur clusters in metalloproteins are known to be sensitive to molecular oxygen with dramatic consequences for their biological function. We performed a …
