Abstract

Advances in electronic spectroscopies with femtosecond time resolution have provided new information on the excitonic processes taking place during the energy conversion in natural photosynthetic antennae. This has promoted the development of new theoretical protocols aiming at accurately describing the properties and mechanisms of exciton formation and relaxation. In this perspective, we provide an overview of the quantum chemical based approaches, trying to underline both the potentials of the methods and their weaknesses. In particular three main aspects will be analysed, the quantum mechanical description of excitonic parameters (site energies and couplings), the incorporation of environmental effects on these parameters through hybrid quantum/classical approaches, and the modelling of the dynamical coupling among such parameters and the vibrations of the pigment–protein complex.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
