Abstract:
A model for the photodissociation of ICN in its lowest continuum is developed and is used to predict the partitioning of available energy between translational, rotational and vibrational energies of the recoiling fragments. The model is based on three major assumptions 1 that only one upper electronic state is involved, 2 that light absorption affects only the breaking C-I bond, thus allowing the upper state potential surface to be calculated quasi-diatomically from spectral and thermodynamic data, and 3 that the mechanics of the half collision of the recoiling fragments on this potential surface may be treated as classical to predict the average partitioning between translational, rotational and vibrational energies, and by a classical energy, forced quantum oscillator approximation to predict the partitioning between vibrational states. The model predicts that most of the available energy will go into translation, which is consistent with flash photolysis studies and with crude measurements of the photofragment spectrum. Author
