Experimental and theoretical study of Criegee intermediate (CH2OO) reactions with n-butyraldehyde and isobutyraldehyde: kinetics, implications and atmospheric fate

The reactions of the simplest Criegee intermediate (CH 2 OO) with n -butyraldehyde ( n BD) and isobutyraldehyde (iBD) were studied at 253–318 K and (50 ± 2) torr, using Cavity Ring-down spectroscopy (CRDS).
