Abstract: We present a QCD-motivated approach to the analysis of polarized Bjorken sum rule in the nonperturbative infrared region Q2 < 1 GeV2. In this approach, we use the Gerasimov–Drell–Hearn sum rule as a boundary condition and move from the region of large momentum transfers to the low Q2-region. We show that the developed approach works well and note a possible problem with the Jefferson Lab data at Q2 < 0.1 GeV2.
