The strong coupling constant is calculated using the three-point QCD sum-rule method. We use correlation functions to obtain these strong coupling constants with contributions of both and mesons as off-shell states. The contributions of two gluon condensates as a radiative correction are considered. The results show that and in the and off-shell state, respectively.
