We present a lattice investigation of heavy-light mesons in the quenched approximation, using non-relativistic QCD for the heavy quark and a clover improved Wilson formulation for the light quark. A comprehensive calculation of the heavy-light spectrum has been performed for various heavy quark masses around the b. Our results for the Bₛ-Bd splitting agree well with the experimental value. We find the Λb-B splitting to be compatible with experiment, albeit with large error bars. Our B*-B splitting is slightly low, which could be explained as an effect of quenching. For the first time, we are able to estimate the mass of P states at the B and compare them with experiment.
