Paper Abstract

Relaxation of the electronic energy in the active medium of the chemical oxygen-iodine laser (COIL) causes non- equilibrium population of vibrational levels of oxygen. It is found that the fraction of vibrationally excited oxygen can reach several of percent in the oxygen stream. The rate relaxation of vibrational energy of oxygen is limited by the exchange between oxygen at the first vibrational level and the bending mode of water. A simple formulas for the population of singlet oxygen vibrational levels at the output of a singlet-oxygen generator are found. It is noted that the EE energy transfer between singlet oxygen and molecular iodine stimulated by the vibrational excitation may be of considerable importance in the kinetics of iodine dissociation.
