We present a number of exact relations for the heavy quark limit and develop an analytical 1/mQ expansion for heavy mesons in the 't Hooft model. Among the new results are the relation 3μ_π²=Λ²-mₛₚ²+β²,1/mQ corrections to the decay constants, to the kinetic expectation values, and 1/mQ² nonperturbative corrections to the →BD amplitude at zero recoil. The properties of the IW functions are addressed and the small velocity sum rules are verified.
