Short summary

We report the first kinetic study of a key atmospheric nighttime oxidant (NO₃) with one-molecule thin organic layers at the air–water interface. Organic molecules were chosen to establish the impact of head group, aliphatic chain length and saturation. We show that NO₃ may dominate degradation at night, retention of the organic character varies strongly and atmospheric lifetimes are longer than those determined at the interface – a key motivation for further experimental and modelling studies.
