Abstract
Values of the binary absorption coefficients are obtained for the region of Herzberg photodissociation continuum in mixtures of oxygen with various foreign gases X, where X - Ar, Kr, Xe, N2, N2O, CH4, C3H8, CO2, NH3, NF3, SF6, CF4, C2F6, C3F8, CF3H, CF3Cl, CF3Br, CF2ClH, CF2Cl2 - group I (the ionization potential of molecules >= 11 eV) and C2H4, CF3I, C2F5I - group II (the ionization potential < 11 eV). The induced absorption of the mixtures of O2 with gases from group I is found to result from the Herzberg III band of oxygen. The obtained regular dependence of the intensity of induced absorption in an O2 - X pair on the ionization potential of a molecule X, confirms the hypothesis that excited electronic states of the ionic type of the molecular pair serve as the main intensity source for the Herzberg III band. The long-wavelength wing of the charge transfer band of the O2 - X pair is shown to contribute to the induced absorption of the mixtures of O2 with gases from group II.
