We have investigated the mechanism of proton transfer in the lowest photoexcited state of 7-hydroxyquinoline·(NH3)3 using TDDFT based molecular dynamics. We observe a concerted mechanism according to which all protons are transferred simultaneously in a fast process (∼100 fs) that amounts to the net transport of one proton from the oxygen to the nitrogen of 7-hydroxyquinoline. In addition, the observed proton transfer pathway involves all three ammonia molecules and not only two as previously proposed. These differences arise from dynamical effects that occur at finite temperature. Our simulations provide a detailed time-resolved description of the proton transfer reaction mechanism for a prototypical molecular cluster and thus help to shed further light on the nature of this important and ubiquitous process.

Physical Chemistry Chemical Physics

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.
