Abstract: It is shown that the approximate constancy of the quantity δm2 = mv2−mv2, among vector and pseudoscalar mesons (Qq) is valid in the infinite mass limit that has been proposed recently. This allows an estimate of the values of the pseudoscalar decay constants to be given. Although there is a large uncertainty in the estimates, depending on how they are normalized, the ratios of the decay constants are in good agreement with the lattice calculations.
