Chloryl nitrate:  a novel product of the OClO + NO3 + M recombination.
The products of the reaction of OClO with NO3 were investigated between 220 and 298 K using a flow reactor and infrared, visible, and ultraviolet analysis.  At temperatures below 250 K new infrared and ultraviolet absorption features were observed and assigned to the novel compound chloryl nitrate (O2ClONO2).  Additionally, ClO and NO2 were observed as reaction products, indicating the existence of a second reaction channel.  O2ClONO2 formation predominates at temperatures below 230 K.  The reaction rate constant at 220 K is estimated to be on the order of 10(-14) cm3 molecule-1 s-1 in 1-5 Torr of helium.  These observations suggest that O2ClONO2 may exist in the terrestrial stratosphere.
