摘要: The reaction between CH3O2 and OH radicals has been shown to be fast play an appreciable role for the removal of radials in remote environments such as marine boundary layer. Two different experimental techniques have used here determine products this reaction. HO2 yield obtained from simultaneous time-resolved measurements absolute concentration CH3O2, OH, by cw-CRDS. possible formation a Criegee intermediate measured broadband cavity enhanced UV absorption. A ϕHO2 = (0.8 ± 0.2) upper limit ϕCriegee 0.05 determined reaction, suggesting minor methanol or stabilized trioxide product. impact on composition layer implementing these findings into box model utilizing Master Chemical Mechanism v3.2, constraining conditions found at Cape Verde Atmospheric Observat...
