We present a study of the charmonium spectrum including higher spin and exotic states. Our simulations are performed on Nf=2 dynamical lattices using the clover wilson action. In order to access excited states we apply a variational method with a basis of highly optimized operators. Furthermore we include disconnected diagramms by utilizing improved all-to-all-propagators.
