  Assuming the QCD multipole expansion is applicable to hadronic transitions of
Upsilon(3S) into lower level bottomonia, we consider the possibility that
Upsilon(3S) has a D-wave component. This assumption leads to a natural
explanation of the pi-pi spectrum in Upsilon(3S) -> Upsilon(1S) pi-pi.
Consequences of this assumption on other hadronic and radiative transitions of
Upsilon(3S) are also discussed in the same context.
