Abstract	The O$_{2}$-CCT absorption spectra of bicomponent systems were measured. The influences of various organic compounds as well as the component concentration on the O$_{2}$-CCT formation ability were investigated. The results show that if the difference of O$_{2}$-CCT formation ability between the two components is rather large, such as the benzene/ isopropyl ether system, only the O$_{2}$-CCT absorption of benzene appears, which arises from its higher O$_{2}$-CCT formation ability. If the difference of O$_{2}$-CCT formation ability is small, such as the isopropyl ether/ethanol system and the dioxane/isopropyl ether system, it is rather easy to form a dynamic equilibrium of two O$_{2}$-CCT between the two components, then only one absorption peak appears in the whole concentration range as a result of the repeated addition of the two kinds of O$_{2}$-CCT absorption. If the difference of O$_{2}$-CCT formation ability is in medium compared with the two cases above, such as the dioxane/ethanol system, there are two kinds of$_{2}$-CCT absorption of dioxane and ethanol in the same system in the form of an equilibrium, then two absorption peaks can be detected in the middle concentration range as a result of the repeated addition of the two kinds of$_{2}$-CCT absorption.
