Abstract
We compute the O(α s ) corrections to the Wilson coefficient of the chromomagnetic operator in inclusive semileptonic B decays. The results are employed to evaluate the complete \( {{{{\alpha_s}\Lambda_{\mathrm{QCD}}^2}} \left/ {{m_b^2}} \right.} \) correction to the semileptonic width and to the first moments of the lepton energy distribution.
