In this paper we compute, within in the context of a relativistic quark model, the Isgur-Wise functions for exclusive semileptonic B → Xc decays, where Xc is any charmed mesons with total spin J=0,1,2 or one of their first excited states. The relevant matrix elements are computed by a direct numerical integration, in coordinate space, of the convolution of the wave function of the B meson at rest and the wave function of the Xc meson, boosted according with its recoil factor. Our results are compared with other predictions found in the existing literature.
