We study the 5D Rarita-Schwinger fields to describe spin 3/2 baryons in AdS/QCD. We calculate the spectrum of spin 3/2 baryons (\ensuremathΔ resonances) and their form factors, together with meson-baryon couplings from AdS/QCD. The transition form factors between \ensuremathΔ and nucleon are evaluated. Both pion and rho meson couplings have the same origin in the bulk and hence are unified. The numerical values for the meson-baryon transition couplings are roughly consistent with the values obtained from other methods. We also predict the numerical values of some new couplings associated with \ensuremathΔ resonances.
