ChemInform Abstract
The major product of the gas phase reaction of Br atoms with NO2, studied in the range 215—300 K, is found to be the cis isomer of BrONO (> 75% yield), which is identified and quantified by its N=O stretching fundamental at 1660 cm-1. Although rapid decomposition back to Br and NO2 occurs at room temp. (lifetime <1 s), BrONO can be detected at temperatures ≤263 K. Isomerization of BrONO to BrNO2 becomes important at low temp. and the rate coefficient for this process is studied as function of temperature and pressure. Evidence is also given for rapid reactions of Br with both BrONO and BrNO2.
