A modification of QCD sum rules for the correlation function <0chemically bondT(j/sub ..mu../(x), j/sub ..nu../(0))chemically bond..pi..> with allowance for the axial anomaly is used to determine the coupling constant g/sub ..omega..//sub rho//sub ..pi../. The calculated value g/sub ..omega..//sub rho//sub ..pi../ = 16 GeV/sup -1/ is in good agreement with estimates of the vector-dominance model. It is shown that the usual procedure gives a result appreciably lower than the experimental value.
