   <hidden TTP96-54  Resonance Contributions to the Electromagnetic Low Energy Constants of Chiral Perturbation Theory > The effective chiral Lagrangian of the strong and electromagnetic
 interactions of the pseudoscalar mesons at low energies depends on a
 set of low energy constants. We determine the contributions to the
 electromagnetic coupling constants at order $O(e^2 p^2)$, which arise
 from resonances within a photon loop. We give some implications of our
 results, in particular we discuss in detail the effects on the
 corrections to Dashen's theorem.
