Experimental study of iodine dissociation in active medium of oxygen-iodine laser

Results of experiments on dissociation of iodine molecules in oxygen-iodine laser medium are presented. Rates constant of key reactions have been reexamined. The experiments confirmed mechanism of iodine dissociation proposed in (J. Phys. Chem., 87, 2348 (1983)). The experiments did not reveal the contribution of vibrationally excited oxygen molecules or three body reactions in the dissociation of iodine.
