Abstract
We present results for Charmonium spectroscopy using 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 states. Splittings between the lowest , and states are given and we have accurate values for the state hyperfine splitting and the fine structure. Agreement with experiment is good - the remaining systematic errors are discussed.
