Excited states articles from across Nature Portfolio

Excited states are those quantum states of an atom or a molecule with more energy than the ground state. The understanding of excited states and their relaxation to lower energy states plays an important role in spectroscopy and also lies at the heart of photochemistry.

    Photoredox catalysts offer a promising approach to performing reactions with high energetic requirements, however, the influence of solvent and counter ions is not fully understood. Now, a microwave-based technique is shown to give direct insight into their effects on charge reorganization during catalysis.

    Ultrafast singlet fission has the potential to facilitate highly efficient photovoltaics through the multiplication of excitons in organic molecular architectures. Here, we consider the interplay of molecular structure and intermolecular coupling toward enabling ultrafast singlet fission and discuss open questions in the field.
