要旨

In this work we compute the S1 potential energy curve responsible for stilbene cis–trans photoisomerisation employing the RASSCF approach, since the standard CASPT2//CASSCF protocol appears to be unsatisfactory in describing the stilbene S1 state. We find that RASSCF calculations, which are based on relatively few (but well chosen) configurations, produce qualitatively correct results and accurate relative excited state energies, both in the twisted and in the cis and trans regions of stilbene.

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.
