在对流层中,气相Criegee中间体(Os)的命运被认为是由它们与水分子的反应决定的。在这里,它表明,在水/乙腈(W/AN)溶液的表面上原位产生的CI竞争性反应与毫摩尔羧酸。本实验通过在线电喷雾质谱法探测暴露于O-3(g)的W/AN微射流中α-蛇麻烯和β-香芹烯表面上的Cls化学,
In the troposphere, the fate of gas-phase Criegee intermediates (Os) is deemed to be determined by their reactions with water molecules. Here it is shown that CIs produced in situ on the surface of water/acetonitrile (W/AN) solutions react competitively with millimolar carboxylic acids. Present experiments probe, via online electrospray mass spectrometry, Cls' chemistry on the surface of alpha-humulene and beta-caryophyllene in W/AN microjets exposed to O-3(g) for
