The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Evaluation of Weak Interactions Between the Ring Component and Axle Component in [2]Rotaxanes With 1,3‐Diyne Moiety

open access: yesChemistry – A European Journal, EarlyView.
The rotaxane architecture is a powerful tool to probe weak interactions. The interaction between the ring component and the axle components was estimated by quantitative conformational analysis of the rotaxanes by 1H NMR spectroscopy. Theoretical calculations revealed that C─H⋯N interactions and steric effects would be responsible for the preferred ...

Coupled heat and mass transfer in reactive parallel‐plate flow: A perturbative Graetz model with modal symmetry and Arrhenius kinetics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.
