Final State Distributions from Unimolecular Reactions: Implications of a General Theorem

A recently derived theorem connects the final state distribution following unimolecular decomposition of an isolated molecule with that which one might measure in a heat bath. The ramifications of this relation and technical aspects of its implementation are examined here. Useful relations for rotat...

Zusammenfassung:A recently derived theorem connects the final state distribution following unimolecular decomposition of an isolated molecule with that which one might measure in a heat bath. The ramifications of this relation and technical aspects of its implementation are examined here. Useful relations for rotational and kinetic energy distributions are derived. Expressions for the energy and angular momentum dependence of branching ratios are presented. 24 refs., 3 figs.
