A model of the iodine dissociation in the presence of O­2 1Δ g is proposed. This model assumes the excitation of molecular iodine by excited iodine atoms into high vibrational levels, followed by the dissociation of iodine in these levels, occurring after a collision with O2 1Δ g . The iodine atons are quickly excited by O2 1Δ g , allowing the mechanism of dissociation to take place as soon as some iodine atoms are produced. The dependence of some reaction rates with the vibrational quantum number is reported; a comparison with different experimental results and with other models is given.
