Using the large NC approximation we have constructed the most general chiral resonance Lagrangian in the odd-intrinsic parity sector that can generate low-energy chiral constants up to NNLO. Integrating out the resonance fields these constants are expressed in terms of resonance couplings and masses.
The role of eta prime is discussed and its contribution is explicitly factorized. We have studied several phenomenological implications, for example, a prediction for the pi0-pole contribution to the muon g-2 factor.
