The q{sup 2} dependence of the {rho} - {omega} mixing amplitude is analyzed with the use of the QCD sum rules and the dispersion relation. In going off shell the mixing decreases, changes sign at q{sup 2} {approx_equal} 0.4 m{sub {rho}}{sup 2} > 0, and is negative in the space-like region. Implications of this result to the isospin breaking part of the nuclear force are discussed.
