Abstract

In contrast to its strong presence in gas-phase reactions, the formyl radical, HCO, has never been identified in aqueous solution. Here the photolysis of aqueous formate anions, HCOO−(aq), following the excitation of the (nπ*) transition at 200 nm is studied by infrared femtosecond transient absorption spectroscopy with the purpose of identifying the aqueous formyl radical photoproduct, HCO(aq). However, HCO(aq) is not observed. The experiments indicate that HCO(aq) exists for less than one picosecond before it reacts with the surrounding water molecules.

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.
