Mass splittings between isodoublet meson pairs and between 0^\ensuremath- and 1^\ensuremath- mesons of the same valence quark content are computed in a detailed nonrelativistic model. The field-theoretic expressions for such splittings are shown to reduce to kinematic and Breit-Fermi terms in the nonrelativistic limit. Algebraic results thus obtained are applied to the specific case of the linear-plus-Coulomb potential, with resultant numbers compared to experiment.
