In this work, we present a theoretical study of the mechanism of double proton transfer in formamide, formamide–thioformamide and thioformamide dimers. The reaction mechanisms were analyzed in terms of the energy profile and novel concepts such as the reaction force profile and reaction electronic flux, along with local electronic properties such as NBO analysis. All systems were characterized computationally using DFT/B3LYP 6-311G** on Gaussian09. These results show that the electronic processes take place mostly in the transition state for all the systems; in the formamide and thioformamide dimers, electron transfer has a synchronic nature, while the electron transfer is asynchronic in the formamide–thioformamide dimer.

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.
