We present first results for Bc spectroscopy using Lattice Non-Relativistic QCD (NRQCD). For the NRQCD action the leading order spin-dependent and next to leading order spin-independent interactions have been included with tadpole-improved coefficients. We use multi-exponential fits to multiple correlation functions to extract ground and excited S states and give accurate values for the S state hyperfine splitting and the P state (Bc∗∗) fine structure, including the effects of 1P1/3P1 mixing.
