Overview

Randomized trial investigates gas-phase reaction kinetics in isobutylamine, suggesting atmospheric relevance.

Key Points

  • This research aims to understand the gas-phase reaction kinetics between the Criegee intermediate and isobutylamine.
  • Utilized cavity ring-down spectroscopy to measure reaction rates in a temperature range of 278–318 K.
  • Conducted computational analysis at the CCSD(T)-F12/cc-pVTZ-F12 level of theory using MESMER.
  • Determined rate coefficients under pseudo-first-order conditions with varying concentrations.
  • At 298 K, the bimolecular rate coefficient was (6.99 ± 0.18) × 10–12 cm3 molecule–1 s–1.
  • Inverse temperature dependence was observed for rate coefficients across the experimental range.
  • Experimental and theoretical results from computational methods were in good agreement.
