Presently the quarkonium spectrum, written in terms of the quark MS-Mass, is known at O(α S/ 3m) accuracy. We point out that in order to achieve O(α S/ 4m) accuracy it is sufficient to calculate further (I) the O(α S/ 4m) relation between the MS-Mass and the pole-Mass, and (II) the binding energy at O(α S/ 5m) in the large-β 0 approximation. We calculate the latter correction analytically for the 1 S-State and study its phenomenological implications.
