Superconvergence sum rules have been obtained for the invariant amplitudes of the elastic as well as inelastic and exotic as well as nonexotic scattering processes involving pions and charmed baryons. The assumption of saturating these sum rules by the known low-lying states is then exploited to determine the pion-- charmed-baryon coupling strengths.
