In particular, we compute the coefficients of the decay operators that have the same quantum numbers as the heavy quarkonium. We also confirm previous calculations of the order-v^2 corrections to these rates. We find that the v expansion converges well for the decays of ^1S_0 heavy quarkonium and for the decay of ^3S_1 heavy quarkonium into a lepton pair.
