Abstract
FTIR evidence is provided for the identification of [H2OCl](+) as an i ntermediate in the ionization of chlorine nitrate on water-ice at the stratospherically relevant temperature, 180 K. The result has importan t implications for the mechanism by which chlorine is reactivated by p olar stratospheric clouds and suggests that the function of water mole cules is to reduce the activation energy-barrier for chlorine nitrate bond cleavage on the ice.
