  We study the strong interactions of the L=1 orbitally excited baryons with
one heavy quark in the framework of the Heavy Hadron Chiral Perturbation
Theory. To leading order in the heavy mass expansion, the interaction
Lagrangian describing the couplings of these states among themselves and with
the ground state heavy baryons contains 46 unknown couplings. We derive sum
rules analogous to the Adler-Weisberger sum rule which constrain these
couplings and relate them to the couplings of the s-wave heavy baryons. Using a
spin 3/2 baryon as a target, we find a sum rule expressing the deviation from
the quark model prediction for pion couplings to s-wave states in terms of
couplings of the p-wave states. In the constituent quark model these couplings
are related and can be expressed in terms of only two reduced matrix elements.
Using recent CLEO data on $\Sigma_c^{*}$ and $\Lambda_{c1}^+$ strong decays, we
determine some of the unknown couplings in the chiral Lagrangian and the two
quark model reduced matrix elements. Specific predictions are made for the
decay properties of all L=1 charmed baryons.
