The heterogeneous reactions of nitrogen oxides such as NO{sub 2} and N{sub 2}O{sub 5} with NaCl in seasalt aerosols are of potential importance in atmospheric chemistry. Thus they form photochemically unstable gaseous chlorine compounds such as ClNO in the case of the NO{sub 2} reaction, and ClNO{sub 2} in the N{sub 2}O{sub 5} reaction. Photolysis of the ClNO and ClNO{sub 2} forms chlorine atoms which will initiate various atmospheric reactions including oxidations of organics. This paper will present initial results achieved in a new experimental approach in which the reactive gases were passed over the salt surface and the formation of surface species such as NO{sub 3} followed by DRIFTS. The implications for the chemistry of seasalt particles in the troposphere will be discussed.
