We obtain limits on the anomalous magnetic and electric dipole moments of the ν τ through the reaction and in the framework of a 331 model. We consider initial-state radiation, and neglect W and photon exchange diagrams. The results are based on the data reported by the L3 Collaboration at LEP, and compare favorably with the limits obtained in other models, complementing previous studies on the dipole moments.
