Dissociation of I{sub 2} and the vibrational kinetics in the oxygen-iodine medium
- Samara Branch of the P.N. Lebedev Physics Institute, Russian Academy of Sciences, Samara (Russian Federation)
The comparative analysis of the processes responsible for dissociation of molecular iodine in the oxygen-iodine medium is made. The rate of relaxation of vibrationally excited oxygen in the O{sub 2}-I{sub 2}-H{sub 2}O medium is shown to be limited by the VV energy exchange between oxygen and water molecules, and the fraction of vibrationally excited O{sub 2} ({nu}=1) in the active medium of the oxygen-iodine laser can reach several tens of percent. It is noted that the VV exchange in O{sub 2}({sup 1{Delta}},{nu}=1)+I({sup 2}P{sub 3/2}){r_reversible}O{sub 2}({sup 3{Sigma}},{nu}=1)+I({sup 2}P{sub 1/2}) reaction may be of considerable importance in the kinetics of formation of the active medium in the oxygen-iodine laser.
