The reactions of IO with HO2, NO and CH3SCH3: Flow tube studies of kinetics and product formation
文献信息

Rate coefficients for the reaction between IO and HO2 and between IO and NO were obtained using a low-pressure flow tube at total pressures of 1.0–2.0 Torr of He, and between 353 and 273 K. Reactants and products were detected using a quadrupole mass spectrometer. The temperature-dependent rate coefficient for the reaction between IO and HO2 is described by k2 = (2.2 ± 0.6) × 10−11 exp{(400 ± 80)/T} cm3 s−1. The temperature-dependent rate coefficient for the reaction between IO and NO is described by k4 = (8.3 ± 2.3) × 10−12 exp{(269 ± 85)/T} cm3 s−1. The rate coefficient at 298 K (and 2.5–2.7 Torr He) for the reaction of IO and CH3SCH3 was found to be k5 = (1.6 ± 0.3) × 10−14 cm3 s−1. At all the temperatures used in this study the only products observed were HOI from reaction (2), NO2 from reaction (4), and CH3S(O)CH3 from reaction (5). The new results for reactions (2) and (4) are compared to existing measurements, and combined with selected data sets to make recommendations for the temperature-dependent rate coefficients.

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.
