The overall rate constant of the BrO + ClO reaction has been measured by the discharge flow mass spectrometry method. The value found at 298 K is k{sub 1} = (1.13 {plus minus} 0.15) {times} 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1}. Branching ratios for two of the three reaction channels were determined from the direct measurements of OClO and BrCl and were found to be (0.43 {plus minus} 0.10) and (0.12 {plus minus} 0.05), respectively. These results are compared with recent literature data and their implication for the polar ozone stratospheric chemistry is discussed.
