The electron spin resonance of MoO3-4 in YVO4 was studied at 4.2K. The Mo5+ has a dxy ground state and is shown to move off the V5+ substitutional site of D2d symmetry to one of four crystallographically equivalent off-center sites of C2 symmetry, located in the 〈110〉 direction. The Mo5+ spectrum is compared to Cr5+ in YVO4 and YPO4 and V4+ in ZrSiO4 and other zircon-like crystals which show dynamic effects that we interpret as tunneling or thermally activated hopping between off-center sites.
