The resonant structure of the four pion final state in the decay tau-->3 pi pi(o)nu(tau) has been analyzed using 4.27 million tau(+)tau(-) pairs colle cted by the CLEO II experiment at the Cornell Electron Storage Ring. A part ial wave analysis of the resonant structure of the tau-->3 pi pi(o)nu(tau) decay has been performed; the spectral decomposition of the four pion syste m is dominated by the omega pi and a(1)pi final states. The mass and width of the rho' resonance have been extracted from a fit to the tau-->omega pi nu(tau), spectral function. We have searched for second class currents in t he decay tau-->omega pi nu(tau) using spin-parity analysis and established an upper limit on the non-rector current contribution.
