Quasi-classical dynamics calculations and state-selected rate coefficients for H+H2(v,j)→3H processes: application to the global dissociation rate under thermal conditions

The quasi-classical trajectory method has been applied to the calculation of a complete set of cross-sections for the H+H2(v,j)→3H processes, using the LSTH potential energy surface. The results have been used to get the global dissociation rate of molecular hydrogen induced by atomic hydrogen, obtaining good agreement with experimental results.
