Short summary
The reactions between electronically excited NO2* and NO3* with water vapour were studied using laser excitation of NO2 (532–647 nm) or NO3 (623–662 nm). No evidence for OH production was observed in either reaction. The reaction of NO2* with water is not a significant source of OH in the atmosphere.
