We have made 7Li and 51V NMR measurements on a single crystal to investigate the local symmetry and the charge disproportionation in the metallic phase of the quasi-one-dimensional conductor β-Li0.33V2O5. The electric quadrupole tensors at the Li sites are determined and the Li ordering is discussed on the basis of the recent X-ray diffraction results. We also report the temperature dependence of the 51V Knight shift and the 51V nuclear spin-lattice relaxation rate, indicating the presence of the charge disproportionation even in the metallic phase.
