Abstract

The dissociation of I by 02 in a Chemical Oxygen Iodine Laser (COIL) cannot occur with a single colision. A two-step model where the excited intermediate species is identified with the vibrational states of 12x(0+g), with V between 30 and 43, has been proposed. The existence of these species has already been checked by using laser fluorescence excitation spectroscopy. The improvements of this experiment will permit one to make absolute measurements of the iodine vibrational level populations along the reaction zone and to know excitation rates of I2 by O21 •
