Abstract : The rate of dissociation of HBr has been measured at temperatures in the range of 1500 to 2700K in shock waves by recording the light emitted when two Br atoms combine to form Br2(singlet Pi(u)). The experiments show that the activation energy for HBr dissociation cannot be substantially different from the HBr bond energy. The rate coefficients for the dissociation of Br2 by Ar, He, and Br were determined by shock heating mixtures of Br2 and Ar or He. The temperature and concentration dependence of the light emitted behind bromine-argon shocks have been examined. (Author)
