Silicon monoxide (SiO) is injected directly into the Earth’s upper atmosphere by ablating meteoroids. SiO is also produced by the reaction of atomic Si (another ablation product) with O2 and O3. The reactions of SiO with several atmospherically relevant oxidants have been studied by the pulsed laser photolysis of a Si atom precursor in the presence of O2, followed by time-resolved non-resonant laser-induced fluorescence of SiO at 282 nm. This yielded: k(SiO + O3, 190–293 K) = (4.4 ± 0.6) × 10−13 cm3 molecule−1 s−1; k(SiO + O2 + He, 293 K) ≤ 3 × 10−32 cm6 molecule−2 s−1, k(SiO + O + He, 293 K) ≤ 1 × 10−30 cm6 molecule−2 s−1, k(SiO + H2O, 293 K, 4–20 Torr) ≤ 4 ×10−14 cm3 molecule−1 s−1, and k(SiO + OH, 293 K, 4–20 Torr) = (5.7 ± 2.0) × 10−12 cm3 molecule−1 s−1. These results are explained by combining ab initio quantum chemistry calculations with transition state theory and RRKM theory. An upper limit of 5 × 10−13 cm3 molecule−1 s−1 for the reaction SiO2 + O → SiO + O2 was determined, but calculations indicate the existence of a high barrier (104.7 kJ mol−1) which will make this reaction very slow at mesospheric temperatures.

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.
