  The formalism and applications of chiral perturbation theory for hadrons
containing a single heavy quark are discussed. We emphasize the utility of
working directly with the velocity dependent ``super'' fields which appear in
the chiral Lagrangian and whose interactions manifestly preserve heavy quark
spin symmetry rather than their individual spin components. Chiral logarithm
corrections to meson and baryon Isgur-Wise functions are found using these
fields.
  We also identify a unique dimension-five operator which couples the axial
vector Goldstone current to the heavy antitriplet baryon field $T_\Q$. We then
compute the differential rate for the spin symmetry violating decay $T_b(v) \to
T_c(v') \ell \bar{\v}_\ell \pi$. The ratio of this decay rate to that for the
corresponding pure semileptonic transition can be studied away from the zero
recoil point.
