To leading order in alpha(s), the leading and non-leading 1/m(b) corrections to the strong coupling constant g(B**B pi) of the excited B** meson are calculated in the framework of QCD spectral moment sum rules in the full theory. Our prediction is in good agreement with the light-cone QCD sum rule result.
