Abstract

Reactive quenching of OH(A 2Sigma+,v=0) by D2 forming HOD+D was studied in crossed molecular beams. The D atom products are primarily forward scattered relative to the incident D2. The dominant mechanism involves a direct reaction from relatively large impact parameters with approximately 88% of the available energy appearing in HOD internal excitation.
