Abstract:

This paper addresses the following questions 1 Under what conditions, if any, is intramolecular energy exchange slowrapid relative to other processes, for example photon emission, or isomerization, or fragmentation 2 How does the intramolecular energy exchange depend on the energy of the molecule and the nature of the initial excitation 3 If there are situations for which intramolecular energy exchange is slow relative to chemical reaction, why does this behavior occur Does it derive from special characteristics of the molecular force fields Are there dynamical or symmetry restrictions on the spectrum of states in these cases Are these special situations commonly or rarely found 4 Given the answers to 3, can we devise excitation methods and reaction conditions that pemit enchancement of the selectivity of the chemistry that follows Author
