Abstract

The values of the binary absorption coefficient μ₁₂ for an O₂ - Ar pair in the region of the Herzberg photodissociation continuum (200 - 230 nm) have been measured in the temperature range 295 - 120 K. It was found that for the temperatures from 295 K to 160 K the values of μ₁₂ demonstrate rather weak temperature dependence, while as the temperature decreases from 160 K to 120 K, the values of μ₁₂ increase by ~ 15%. Transition dipole moment function of exponential type was proposed to describe the observed temperature dependence of the values of the binary absorption coefficient μ₁₂ for an O₂ - Ar pair in the Herzberg III band of oxygen. Comparison of the temperature dependences of the binary absorption coefficients for an O₂ - Ar pair and for an O₂ - O₂ pair was carried out.
