Rate coefficient of the reaction CH₂OO + NO₂probed with a quantum-cascade laser near 11 μm

Abstract

Employing a cw quantum-cascade laser coupled with Herriott mirrors to probe CH₂OO, we report a rate coefficient<italic>k</italic>= (1.0 ± 0.2) × 10⁻¹²cm³molecule⁻¹s⁻¹for the reaction CH₂OO + NO₂at 298 K, which is much smaller than literature values.
