Abstract
New fits to the molecular iodine dissociation rate data of Heidner et al. Were obtained with the goals of achieving a better overall representation of the experimental data and determining a set of rate constants compatible with the assumption that the dissociation intermediate I2dagger is vibrationally excited I2. Improved rate constants were obtained that are significantly different from those used in current computational models of COIL systems. While the new rate constants provided a better representation of the experimental dat, troubling discrepancies remain. New reactions involving electronically excited iodine (I2*) were then added to the model in an attempt to resolve these discrepancies. Preliminary calculations indicate that I2* kinetics provide only a minor path to dissociation and that these model deficiencies will not be resolved by adding electronically excited iodine channels.
