Single water-molecule catalysis in the glyoxal + OH reaction under tropospheric conditions: Fact or fiction? A quantum chemistry and pseudo-second order computational kinetic study

► A single water molecule does not catalyze the glyoxal + OH reaction ► VOC-water complexation step is essential in the determination of the water-assisted glyoxal + OH reaction. ► Pseudo-second-order kinetics must be used in the determination of the water-assisted glyoxal + OH reaction.
