  Although no asymptotic heavy quark spin symmetry, and even more no flavor
symmetry, are expected for systems such as quarkonium, a numerical discussion
shows that for some processes and in a preasymptotic region which may roughly
include charmonium and bottomonium, the use of the spin-symmetry may be useful
in conjunction with chiral symmetry for light hadrons (soft-exchange-
approximation regime, SEA). We continue our discussion of hadronic transitions
in the SEA-regime by studying in particular chiral breaking transitions such as
$~^3P' \to ~^3P\pi^0$, $~^3P\eta$, level splittings and transitions which break
both chiral and spin symmetry, such as $\psi ' \to J/\psi \pi^0$, $J/\psi
\eta$, and $~^1P_1 \to J/\psi \pi^0$.
