On product state distributions in triatomic unimolecular reactions - Part II. Processes governed by non-linear bending forces

Recently, we derived a simple dynamically corrected statistical treatment of state distributions in the products of triatomic unimolecular reactions involving efficient energy transfers between rotation and translation motions en route to products. The reactions considered were those for which transfers are mainly due to the force responsible for the bending motions of the reagent molecule. Our treatment was initially devoted to processes involving a linear bending force in the region of the transition state. It is now extended to the case where this force is non-linear and is applied to the processes O2H (D, T) --> O-2 + H ( D, T).
