The total radiative transition probabilities of rovibronic levels
of B, C, B' and D states of molecular hydrogen are calculated with emphasis
on the dissociation fraction and the kinetic energy released
in the continuum radiation process. The
mixing percentages of B, C, B' and D adiabatic
states are also given. The data are calculated with the detailed
transition probabilities obtained by Abgrall et al. (1993, 1994).
We have included, in the present analysis, results
obtained by using a recent
ab initio transition moment for D - X which comprises
a larger range of internuclear distances.
The related data on individual transition probabilities
may be obtained on request.
