Abstract

The exothermal reaction O + O₃ - 2O₂ is found to be accelerated when ozone molecule vibrations are excited by cw CO₂ laser emission when P_Ar = 3 Torr, T = 300 K in a 0.8 cm i.d. vessel. With a laser irradiation intensity of ≈15 W/cm² this acceleration made up ≈40% as compared with the equilibrium reaction. Vibrational relaxation of ozone molecules is studied by the method of saturated absorption. The relaxation time of population difference for (000) and (001) levels, T₁ = (3.8 ± 1.7) × 10^-4 s, and the transversal relaxation time, T₂ ≈4 × 10^-8 s Torr/P, are measured. T₁ is found to be practically independent of pressure at P = 1-15 Torr.
