It is shown that quark mass dependence induced by one-loop corrections to the Breit–Fermi spin-dependent one-gluon-exchange potential permits an accurate determination of heavy–light meson masses. Thus the Ds(2317) is a canonical cs¯ meson in this scenario. The multiplet splitting relationship of chiral doublet models, M(1+)−M(1−)=M(0+)−M(0−), holds to good accuracy in the D and Ds systems, but is accidental. Radiative transitions and bottom flavoured meson masses are discussed.
