Temperature dependence of the binary absorption coefficient for the mixture of oxygen with argon in the region of the Herzberg III band of oxygen (220 to 270 nm)

摘要

Values of the binary absorption coefficient $mu$-12$/ are obtained in the region of the Herzberg III band of oxygen (220 - 270 nm) for the mixture of oxygen with argon in gas phase for the temperature interval 160 - 295 K and in liquid phase - for T $EQ 141 K. The values of $mu$-12$/ are found to remain constant to within 10% in the whole temperature range studied. The absence of the temperature dependence of the binary absorption coefficient $mu$-12$/ gives evidence that induced absorption of the mixture, governed by it, is determined by absorption of a collision complex O$-2$/ -Ar, which molecules are separated by a distance, comparable with the diameters of molecules.
