Notes:
A flowing–afterglow Langmuir probe apparatus with mass spectral analysis has been used to measure the rate constant for electron attachment to ClONO2 at 300 K. Electron attachment is efficient with a rate constant of 1.1 (±50%)×10−7 cm3 s−1 and proceeds principally through dissociative channels to produce the major product ions NO−2 (∼50%), NO−3 (∼30%), and ClO− (∼20%). The parent ion ClONO−2 and Cl− are also observed in the mass spectra but are at most minor products in the attachment process, ≤2% and ≤6%, respectively. A description of the secondary ion–molecule chemistry that takes place following electron attachment is given. © 1996 American Institute of Physics.
