[en] Salpeter equations are suggested to be used for the description of bound q anti q and qqq systems. The kernel of these equations is assumed to correspond to the quark pair forces with spin structure for both the one-gluon exchange part and the confinement part of the qq-interaction. The partial wave expansion is carried out and the systems of equations for the radial function with given total (J), spin (S) and orbital (L) angular momenta are derived. The states of bound q anti q system with respect to total angular momentum (J), space parity and C-parity are classified
