A mixing of near-threshold quarkoniumlike resonances with heavy meson-antimeson pairs results in an enhancement of heavy quark spin symmetry breaking, since the meson pairs are not eigenstates of the heavy quark spin. The decomposition of P-wave states of meson pairs in terms of the heavy quark pair spin states is considered in the channel with JPC=1--, which is directly produced in e+e^\ensuremath- annihilation. Specific processes are suggested for experimental study of the effects of the mixing with heavy meson pairs and of the internal spin structure of bottomonium and charmonium resonances.
