We investigate the formation of aqueous nitrogen dioxide, NO{sub 2} formed through femtosecond photolysis of nitrate, NO{sub 3}{sup −}(aq) and nitromethane CH{sub 3}NO{sub 2}(aq). Common to the experiments is the observation of a strong induced absorption at 1610 ± 10 cm{sup −1}, assigned to the asymmetric stretch vibration in the ground state of NO{sub 2}. This assignment is substantiated through isotope experiments substituting {sup 14}N by {sup 15}N, experiments at different pH values, and by theoretical calculations and simulations of NO{sub 2}–D{sub 2}O clusters.
