Abstract: The interaction of water with solvents in H_2O-TBP-CCl_4 system and H_2O-p-dio-xan-CCl_4 system is studied with IR method. The absorbances of free water, 1:1 and 1:2 complex are observed and the absorbance frequencies of each species are assigned. In H_2O-TBP-CCl_4 system, there exists not only symmetric 1:2 complex but also unsymmetric one. The water molecule in unsymmetric 1:2 complex is considered to be hydrogen bonded with two kinds of oxygen atom in TBP. And the hydrogen bonds are different in strenghth. Because of diffeent spatial configurations of solvent molecules around water, more than one kind of 1:2 complex exist in H_2O-p-dioxan-CCl_4 system.
