A study is made of the analytic properties of the relativistic scattering amplitude as a function of the momentum transfer and the energy in the quasipotential approach. A spectral representation with respect to the momentum transfer is obtained; like dispersion relations in quantum field theory, this takes into account the relativistic kinematics.
