Scientific paper

Mass splitting between axial and vector $\bar{Q}q$ mesons is considered
within the standard QCD sum rules. In agreement with the first experimental
data on the $B_1$ meson ($J^P =1^{+}$) we find that the splitting for B is
about the same as for D and show that $1/m_Q$ corrections to the meson masses
are small.
