51 V NMR measurements in the uniform state of NaV 2 O 5 are presented. The NMR shift and the electrical field gradient (EFG) were measured at the tetravalent V sites. Observed anisotropy of the NMR shift and the EFG indicates that the d x y -like orbital is occupied. It has been found that the orbital susceptibility in the uniform state is significantly smaller than the residual susceptibility in the spin-Peierls state. The possible origins of this disagreement are discussed.
