Gas-phase reaction rate coefficients of OH radicals with four nitrocatechols have been investigated for the first time by using ESC-Q-UAIC chamber facilities. The reactivity of all investigated nitrocatechols is influenced by the formation of the intramolecular H-bonds that are connected to the deactivating electromeric effect of the NO2 group. For the 3-nitrocatechol compounds, the electromeric effect of the free OH group is diminished by the deactivating E-effect of the NO2 group.
