Abstract
The reactions of the halide anions (F −, Cl −, Br −, and I −), NO 2 −, SF 6 −, CO 3 − and CO 4 − with ClONO 2 have been studied at room temperature in a flowing afterglow apparatus. All these reactions are found to proceed at the collision limit and the experimental data are compared with literature values. The reaction of I − with ClONO 2 was studied at stratospheric pressures and temperatures in view of its use as a possible precursor ion for the measurement of stratospheric N 2O 5+ClONO 2 mixing ratio height profiles by chemical ionization mass spectrometry. No pressure or temperature dependence of the rate constant has been observed. In order to correct the observed rate constants for HNO 3 impurities, the reaction rate constants of F −, Br −, and NO 2 − with HNO 3 have also been determined. In addition, the apparent second-order clustering rate constant of NO 3 − with ClONO 2 in Ar/N 2 and Ar/He mixtures has been measured.
