A sum rule of the scalar and pseudoscalar spectral functions is studied as a possible test for the commutation relations between the fourth component of the axial vector current and the scalar and pseudoscalar densities. Approximating the spectral functions by the one pion and two pion contributions, one finds the sum rule to be badly violated. Author
