Lattice simulation of charmonium resonances with non-zero momentum provides additional information on the relevant two-meson scattering matrices. However, the reduced rotational symmetry in a moving frame renders a number of states with different J^P in the same lattice irreducible representation. The identification of the underlying spin and parity for these states is particularly important for heavy quarkonia, since their spectra contain a number of states with different J^P in a relatively narrow energy region. Preliminary results concerning spin-identification will be presented in relation to our study of charmonium resonances in flight on the Nf=2+1 CLS ensembles.
