A statistical-dynamic model for calculating product state distributions for reactive collisions is presented. For the vibrational-translational coupling Franck-Condon type approximations are adopted which lead to very good agreement with exact quantum calculations in the limit of the collinear arrangement. The rotational degrees of freedom are treated statistically. The energy distribution among vibrational translational and rotational degrees of freedom is discussed as a function of the masses and the attractive part of the potential. Extension from triatomic to polyatomic exchange reactions are considered. A detailed comparison with other simple models is made.
