要旨

An upper limit for the rate coefficient for the reaction of was measured to be 5.7×10−15 cm3 molecule−1 s−1 at 240 K. OH radicals were produced ia pulsed photolysis of a mixture of O3 and H2, ia the reaction of O(1D) with H2, in the presence of an excess of N2O5 with SF6 as the bath gas. The temporal profiles of OH, which followed pseudo-first order kinetics, were monitored by laser induced fluorescence. Concentrations of N2O5 were determined by UV/visible absorption. Using this limit for k1, the potential role of N2O5 loss and conversion to HNO3 due to reaction (1) in the stratosphere is deduced to be negligible relative to known pathways.

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.
