We recalculated the coupling constants of {rho}({omega}){yields}{eta}{gamma} and {eta}{sup '{yields}{rho}}({omega}){gamma} decays especially with loop contributions in the case of axial-vector coupling in the method of QCD sum rules for dimension d=6. A comparison of our prediction on the coupling constants with the result obtained from analysis of the experimental data and calculations done before is performed.
